    THanks for the suggestion but now I am confused with the choices and options. I found Project X and have the folder ProjectX in my subdir of kmttg and it is referenced in the setting file
    I downloaded the latest version and installed this

    When I enabled decrypt and QS fix (this was the new option) the process fails with a message
    "you can't open the application tivodecode because PowerPC applications are no longer supported"
    >>>> Fixed this with after I found the link for the Mac Wiki issue list
    And fixed what has been an erroneous update of Tivodecode....

    There does seem to be some problem with finding directories for location of files - the double click methodology does not work - if you select directories that way they all report errors (no matter where you select)

    Now just waiting for the processing to finish to see what the output looks like having added QS Fix (which I assume is using the Project X code you mentioned)
    And it did and it worked...so this issue is closed but the issue of directory specs not working (another post further down) does seem to be a problem

    THanks

    I'm brand new to kmttg and this forum, so I apologize in advance if this has been covered to death, but I didn't see anything when I searched.

    Everything is going ok with my conversions up to the final re-encode phase, then I see lots of errors, "Skipping frame!" messages, then finally a fatal error:

    "Couldn't realloc frame buffer(idx), abort

    PARSE_MPEG12: add_frames(77539) failed, exit"


    After googling around a little, I found the suggestion to add "-noskip -mpegopts vbuf_size=400" switches in the kmttg issue tracker. So I call the following from a command prompt:

    D:\kmttg_v0p8q\mencoder\mencoder.exe "D:\kmttg_v0p8q\xyz.mpg" -edl "D:\kmttg_v0p8q\xyz.edl" -oac copy -ovc copy -of mpeg -vf harddup -noskip -mpegopts vbuf_size=400 -o "D:\kmttg_v0p8q\xyz_cut.mpg"

    The resulting encode finishes cleanly, but the video is unplayable. I get a brief burst of sound & a static image, then it freezes.

    This doesn't surprise me since I'm just stabbing in the dark for anything that will work, but does anyone know what I might be doing wrong here?

    Thank you.

    If you have VideoRedo then configure kmttg for VideoRedo. Otherwise make sure you have kmttg configured for ProjectX. Then include QS Fix in your task flow. To try it on an already downloaded video from your TiVo switch to FILES tab and add the decrypted (.mpg) file and then enable "QS Fix" task and then the "encode" task. Doing so will run the .mpg through ProjectX which will clean up glitches in the video file before the encode task starts. You need to then make sure for any future downloads that you include "QS Fix" in your set.
    NOTE: Once configured for ProjectX kmttg will also use it for Ad Cut step instead of mencoder which is what is causing you problems.

    Works fine for me on Windows and Linux machines. I don't have Mac to test on.

    Why do you have "TiVoEncoded" directory twice in the path? Sounds like perhaps to me the path you really want is:
    /Volumes/Data/TiVo/TiVoEncoded
    And obviously that directory has to exist and be read/writeable by you.

    Question:

    Where do I look-up the current encoding profiles and how do I change them (the arguments I mean) to create something I want to try for testing?

    Each profile is a separate file under "encode" folder in kmttg installation. You can use a text editor to modify them. Recommended flow is copy existing one to a new name and then edit it.

    FYI, it looks like recent TiVo software updates for Virgin Media broke the RPC capability so that non-TiVo apps no longer work (including the remote in kmttg as indicated in that thread):
    http://community.virginmedia.com/t5...Tivo-Commander-etc/td-p/979929/highlight/true
    I was contacted by a kmttg user in UK about it which is how I became aware of it.

    Looks like TiVo may have tightened up authentication. Looking at the latest TiVo iOS ipa file from iTunes (which is like a zip file) I see there's a "cdata.p12" file there which appears to be a PKCS12 certificate file used for SSL authentication. That variety means a client side password must be given for authentication to work.
    Reason I mention this is I fear the next software update for Series 4 platform in US may well break the RPC capability we have been enjoying the last few months.

    If this happens in the US, what would it mean to KMTTG functionality in your opinion?

    Not good. Without the password for the PKCS12 file there is no way to get past authentication which means none of the kmttg remote functions would work any longer which is the case for latest Virgin Media software already (and TiVo Commander). I was somewhat encouraged though skeptical when TiVo announced renewed intentions for promoting 3rd party developers, but so far I've seen nothing to sway my skepticism, indeed quite the opposite.

    Are the remote functions used for auto transfers? (sorry if this is a dumb question)

    For the most part no. Only if you use "iPad Delete" task (which you have to turn on via config).

    Forgive me if this has been asked/answered in the past - there are a lot of posts in this thread!

    I have kmttg v0p8q configured on my Mac Pro under Mac OS X 10.7.3 (Lion). Working reasonably well, but I've been running into a problem when downloads just seem to stall in the middle of the download. No error message, and kmttg will just wait, and wait, and wait, and no further data is downloaded.

    Any solution for this? BTW - I do have the Resume Downloads toggled in the File menu, though I'm not quite sure how that comes into play.

    Try using Java downloads in config.

    The Resume Downloads start downloads from where you were watching and paused at the point.

    perhaps we should be a little grassroots and have all the kmttg users email tivo about not making such negative changes. i cannot see the upside to locking out users from using the remote functions. what other areas are they trying to lock down that is part ofthis or is it just the remote protocalls and if so, why? they are not charging for their apps so what is the point. i hate that my tivo premiere doesnt have the remote functionality of my now 13 year old replaytv. i mean, if i schedule a show on one tivo and their are conflicts, thru the current tivo app, there is not resolution, but on my 13 yo replay, i can just try and schedule it on the other box. silly.

    on a completely different note, i am still having trouble with adscan hanging at 99 percent in kmttg, i thought this was mostly fixed but it is happening again

    Great program. I can't believe it took me so long to find it.

    I do have one issue I'm hoping someone can help with. While projectX is running--whether it's the remux process or the commercial cut process, it is overloading my hard drive, which makes using the drive for anything else impossible. Is there a way to lower the priority of hard drive activity for projectX or slow it down so it doesn't cause problems?

    As it is, I can't be watching anything while projectX is running. All my media is stored on a second hard drive, so the system remains stable and usable, but I can't watch or listen to any media files.

    Forgive me if this has been covered, but I tried searching and didn't come up with an answer. I've downloaded the latest kmttg and it appears to be working fine, downloading the video, transcoding, etc. However the problem I have is that the resultant video file has very low sound in comparison to the .tivo file. I've tried minimizing all that kmttg is doing is the decryption and still get this issue.

    Whether it's pertinent or not, before finding kmttg I used the directshow dump filter to convert the .tivo files to .mpg files and had similar issues, however it seemed to be more of an issue with the voices rather than all the audio.

    Any ideas? Could it be an issue with codecs or my audio drivers??

    Thanks for any help.

    I would guess codecs. Play back using Videolan VLC which has its own codecs for a different reference point. If you still cannot get adequate sound then I would look at your sound settings. If using Windows right click on speaker in tray and choose Sounds-Playback tab and select the driver properties and then Levels tab. When I had a problem with low sound that's where I managed to fix it.

    I'll d/l videolan and try that. For a test I tried using a completely different computer and got the same results with the lower sound volume. Since I'm having issues on two separate computers I'm guessing the problem is codecs.

    Is there a recommended codec pack or program I should d/l so I have all the right codecs? BTW, this is on an older machine still running XP. Also, since the Athlon chipset doesn't support SSE2 instructions, I have issues using TivoDesktop plus to convert to mobile as well. So hopefully I can find something that works so I can use kmttg.

    Thanks

    Well I figured out why the TiVo files were louder compared against the mpg converted files. TiVo is inserting an audio boost between the decoder and the sound device. It's not present on the mpg file. I'm not sure if there's a way to jack up the audio when decoding the .tivo file or when encoding it as another format. If so, that would be helpful since I ultimately want to u/l these shows to my tablet.

    I've linked screen shots from the codec manager of the two files. It shows the flow chart of how the file is being decoded and played.

    http://www.main.experiencetherave.com/images/tivo_flow_chart.jpg
    http://www.main.experiencetherave.com/images/mpg_flow_chart.jpg


    One other thing I noticed when comparing Tivo desktop to kmmtg is that the new Tivo desktop 2.8.3 seems to be almost twice as fast d/l files. Tivo desktop d/l a file at around 5.75 mb/s, while kmmtg d/l a file at around 3.04 mb/s. These are actual transfer rates based on the file size transferred and the elapsed time of transfer. Are there any settings to boost kmmtg? I read that supposedly tivo desktop v 2.8.3 was supposed to speed up transfer times with the premiere. It seems to work.
