    Sounds like incompatible versions of the module and tivoweb. Get the latest versions of both from the tivoweb site. A new module and old tivoweb will certainly cause this error.

    Note - I *HAVE NOT* looked at module compatibility with the 1.9.4 final release. I'm inclined to think it would be ok, but, it may or may not be compatible.

    Thanks!

    Hi I have recently move to a cable area in the UK. However, my terestrial channels i.e. BBC1, BBC2, ITV, Channel 4, Channel 5 which are normally provided by the aerial onto of the house are proided through the analogue cable box and just arn't encoded. The TIVO is mapping the channels incorrectly for my area. i.e. BBC1 is on RF channel 23, the Tivo is using RF channel 22. What I'm looking to try and do is change BBC1 from RF 22 to RF 23. These channel come up with (AER) next to them in the channel listing as opposed to (SAT). I've uploaded the latest version of channelremap to tivo, but I can only change channel that are preceded with (SAT), the (AER) ones don't come up.
    Is this possible? If not is there another workaround?

    Thanks,

    Barry.

    Antenna channels are apparently stored differently than cable/sat channels. I haven't ever looked at a tivo setup for an antenna connection, so I don't know how thats stored, and consequently the module won't do anything with them.

    Someone else worked around a similar problem which might work for you. Details are in the thread.

    I don't understand what the point of this module is. Why would you want to remap channel numbers? I wish I could use tivoweb to change "received" and "favorite" channels, that would be useful.

    If Tivo thinks A&E is on channel 20 on your system, but its really on channel 21, this module will change the assignment. If Tivo has all your channels correctly mapped, you don't need the module. The mapping is sometimes just wrong, sometimes the cable company changes where each channel is and the Tivo updates it days in advance or days late, sometimes apartment cable systems have completely different channel assignments, at least one person here remodulates channels from the cable assigned location to somewhere else, etc.

    My map is correct 99% of the time, usually the problem only occurs on the rare occasion that the cable company does a wholesale change and the tivo gets updated too early or too late. It prevents me from recording Steel Magnolias on TBS when I was trying to record Kelly's Heros on AMC. :)

    hi

    I am running this against 1.9.4 tivoweb

    Channels in the headend are showing correctly

    Channels added with add-channel.tcl and add-station.tcl are NOT showing!

    Any ideas why?

    When you first setup your tivo, giving it your zipcode and identifying your cable provider, the tivo goes out and pulls down the possible lineups and stores them in MFS. (Setup/Source/Headend/Lineup) "Lineup"

    You then tell the tivo what service package you have (analog basic, analog extended basic, digital basic, digital extended basic, etc.) The tivo then uses the downloaded lineup information to build the list of channels you have. (Setup/Source/Channel) "Active Channel list"

    When you change a channel number assignment with the ChannelMap module, it modifys the channel number in the lineup information. When you commit the changes, it goes through the channels in the lineup information, and changes the number in the corresponding channel object in the active channel list, based on the long and short channel name.

    I would assume that the add-channel hack is incomplete in that it is adding a channel in the active channel list only, leaving the channel "missing" in the lineup information.

    I haven't looked at add-channel, but I think this is likely the problem, and would cause exactly what you are seeing.

    The solution is to either fix add-channel to add a channel in both places, or rewrite the channelmap module to make changes directly in the active channel list.

    that is exactly what add-channel does, it adds it to the active list, NOT to the lineup.

    How hard would it be to add it to a lineup??

    I haven't looked at add-channel, but I don't think the modification would be hard. The lineup object is almost exactly the same as the active channel object - it only has one extra static entry. add-channel is already adding an entry to a list, it would just need to do the same thing in another place with the slightly different object.

    To do it right, you would need to add a little code to be able to specify which lineup to insert the channel into.

    It shouldn't be hard.

    After much difficulty just unzipping this module (IE was corrupting it)I have it working. I now have two questions:

    first, (I know this is probably answered somewhere, but after hours of searching, I give up) I would like to know how to back up my changes so that if something is modified by Tivo, I can revert.

    for my second question I should give a little background. Live in Bermuda where the cable company displays our only 3 local channels (NBC, CBS, ABC), but also displays locals from scattered cities. We have a second NBC from Detroit, Fox from Rochester (???), WB from NYC, etc. I have set up my lineup telling it that I live in Detroit, simply because NBC is my favorite channel. However, Detroit does not have National Geographic and a few other channels I like. It also uses multiple lineup types (digital, analog, premium, etc) which complicates the remap process. What I would like to do, and I have the distinct impression this will be impossible) is to specify no lineup, but pick from every channel Tivo can cover. That way, I could search through for those exact varying locals that I recieve.

    At all possible? If not, is there any other way to grab stations from different cities that you could think of.

    thanks,
    Alex

    Congrats on getting gzip to work.

    On the main ChannelMap page there is a button to save the current channel map, and another to restore the channel map from the saved state.

    It appears that you want to create a custom lineup where you can pick and choose which channels you receive. The module does not provide that functionality. It only allows you to change the channel number for stations in a lineup which you receive.

    did not realize backing up was so easy, that's great to know, thanks.

    as for the picking and choosing out of multiple lineups, I realize that this module lacks that funtionality. However, I was wondering if it would even be possible if I worked with a programming adept friend.

    perhaps I'll start a new thread as it is not specifically related to this module.

    Unfortunately I can never get the backup to stick.

    I used the module to rearrange the cable channels in a shared cable/Dish Net lineup. And every time Dish makes a lineup change (well, TiVo makes one), it wipes my changes. This happens three or four times a week. I've never been able to successfully restore the backup channelmap.

    Thankfully, I only use this setup to record special soccer, cricket and sumo matches, and stuff on local channels I don't receive on DirecTV... so I manually remap every so often.

    I can't really tell why a restore won't work. The backup is saved as a tcl script in the root tivoweb directory called "ChannelMapScript.tcl" When you press the restore button, it just runs that script, with the output going to /tmp/CMS.out

    Perhaps that information will help you figure out what is causing the problem. Works fine over here.

    OK, Zirak, I just made all my changes manually again, committed them and saved the active channels. I went into ChannelMapScript.tcl and verified that the changes are there. We'll see if I can make them stick next time TiVo sends a lineup change down.

    Is there a simple way to script for TiVo to "listen" for a lineup change and automatically revert it back to the saved list?

    By my definition of simple, the key word, I would say no. That isn't to say that it would be hard.

    You could test the save/restore functionality by changing a single channel and committing the change, then do the restore and again commit the change.

    I'll test that. Thanks again for a very useful utility! I'm pretty sure it's user-error, here... hehehe.

    OK, to keep it simple, I changed the first channel on the list (A&E) from 39 to 42 and committed the change. I did not save the active lineup to the script. I then verified that 42 now said A&E. I returned to ChannelMap, and clicked Restore and confirmed. The "It s Done - Commit..." page lists A&E as 42, not the saved 39 as anticipated... WTH am I doing wrong???

    Edit to add: I joe'd into the script and it still shows A&E as 39 and now I'm confused.
