    I think he's referring to the now playing XML, not the xml from the .tivo file. I'm pretty sure it's not doubled in there, but I *think* that the xml there isn't complete..

    anyways, you can look at it by looking (using the beta) in

    <user>/Library/Caches/iTiVo/XMLCache-IP

    I'll try and see if I can use that... but right now I have a bunch of other crap on my plate :(

    is 5 hours normal for 5GB of transfer via ethernet? Is there a faster app, or faster way to do this?

    This question is answered in the iTiVo FAQ: http://code.google.com/p/itivo/wiki/FAQ

    Short version. If you have a Series 3, then yes that's a bit slow. Try selecting a simpler format to convert to, and using a wired connection. If you have a Series 2, then that's probably about as fast as you'll get...

    thanks..

    Any help with this error?

    An invalid public movie atom was found in the movie.

    its a quicktime error after a quicktime format transfer.

    Is this happening for all your transfers or just one? It sounds like a bad mp4 file. Usually that only happens when the mp4 file was not written out completely (did you cancel a transfer partway through?)

    that was the first transfer I tried (no cancel). I deleted the file and it is running again.

    now, atomicparsley crashes about 3 hours into the transfer...

    AtomicParsley is run once the file is fully converted. It has been known to fail on some files. Usually even if it fails the resulting file is still good. However, sometimes that is not the case. You can disable AtomicParsley in the Prefs window (the metadata section) to avoid this problem.

    iTiVo v 1.7.7b3

    Why does a recording downloaded H.264, 10mbps show dimensions of 480 X 480 in QT Player and play at 480x480 but when played in iTunes, it shows the proper aspect ratio?

    Is there some option to make these play at the proper 640x480 in QT Player?

    resolution and aspect ratio are two independent values.

    are you sure it's not 480x480 with a PAR of 4:3 ?

    you can look at it with ffmpeg -i <filename>

    I suspect quicktime is ignoring the PAR.. you may want to view it with VLC or MplayerOSX Extended...
    If that's the case though, I don't know of any way to force quicktime to an aspect ratio..

    Hmmm..., I always thought aspect ratio was calculated from the pixel dimensions. So, during playback, a (proper) player will distort 480x480 into 640x480 to get the Aspect Ratio right?
    I use QuickTime Player Pro because I can edit. I like to save clips on occasion. But I also like to play them back at the proper aspect ratio!

    is 480x480 the native size for TiVo recordings?

    Sort of, although it depends on the codec/container. In the case of mpeg-2 and mpeg-4, a 480x480 with a PAR of 4:3 will use up 640x480 pixels on a machine with square pixels. There are actually several aspect ratios encoded: The pixel aspec ratio will tell it what a pixel looks like. The display aspect ratio will tell it what the target display should be.
    I think it encodes at 480x480 if you use 'high' quality. I think 'best' quality uses 720x480, and 'low' uses something like 240x480 (you'll need to look it up for the actual numbers). If you record from a digital channel it will use whatever resolution it is given.

    The disparities aren't quite that wide. "Best" is, I think, 544x480 on most TiVos -- only the DVD models go to full 704x480 or 720x480 -- and nothing goes as low as 240x480; maybe 352x480?

    This is interesting... As noted previously, I use Multi-Room Viewing a lot. When I use the MRV feature to transfer a recording from one TiVo DVR to another, the recording, as seen in iTiVo, looking at the receiving DVR, shows a date/time corresponding to the time of the transfer, not the recording date.

    Of course, the receiving TiVo itself still shows the correct date/time. Does iTiVo use the file modification date instead of the startTime/stopTime recording metadata?

    For the main display, It uses whatever is enclosed in the CaptureDate tag.

    For the metadata extraction air date, it uses the value in the originalAirDate tag.

    For back-up purposes, I have downloaded hundreds of episode of my wife's soap opera in decrypt format. Later I'll be uploading them again using pyTiVoX.

    Is it possible, from a terminal command line or such, to process these already downloaded files? I'd like to try converting some of them to iPhone format, running them through comskip in the process.

    Can anyone tell me how this might be done? Or would it be easier to just re-download them again from the original DVR, into the iPhone format, using comskip?

    Yes, you can just run terminal commands to take cake of the processing for you.

    The comskip command below will mark commercials in a movie file at movie-file-path and save them to an movie-file-path.edl file:

    Code:
    /Applications/iTiVo.app/Contents/Resources/comskip --ini=/Applications/iTiVo.app/Contents/Resources/comskip.ini --playnice <movie-file-path>
    The mencoder command below will process the movie file at movie-file-path, skip parts indicated in the movie-file-path.edl file, and write out a new movie file movie-file-path-new:

    Code:
    /Applications/iTiVo.app/Contents/Resources/mencoder really-quiet -edl <movie-file-path.edl> -ovc copy -of mpeg -mpegopts format=mpeg2:tsaf:muxrate=36000 -mc 1 -noskip -forceidx -oac copy -hr-edl-seek -o <movie-file-path-new> <movie-file-path>
    You can read up on comskip and mencoder options on the web or simply copy arguments for mencoder out of the "Advanced" tab of the iTiVo preferences dialog. To convert forthe iPhone, set this up in iTivo, and then see what options you should pass to mencoder yourself. You can also use ffmpeg or any other conversion utility you have installed.

    I found downloading without conversion fast and easy. iTiVo also tends to restart the whole process even if it fails on the last step. I simply cobbled a quick Perl script together to check directories for new files downloaded by iTiVo and then mark out commercials and process the files separately. If something fails, then I can fiddle with the already downloaded file as I wish.

    If someone is interested in hacking the script, send me a message, and I'll reply with a copy. I am still fiddling with it a bit. Once I fee a bit more sure, I will release it.

    Dumb question that I haven't seen answered here or in the FAQ:

    When you Subscribe to a show, should existing episodes of the show be added to the download queue, or should I have to go through and manually add each existing show to the d/l queue?

    Apologies if this has been covered, and many thanks for an awesome program.

    Is there a "Keep At Most" option when doing a season pass like on a real TiVo? If not, is it planned? Thanks!

    There is not. I currently do not plan to add support for iTiVo automatically deleting shows you have stored on your computer. I suppose if you feel brave enough you can write a folder action to delete old shows (depending on your definition of old).
