I just tried your update for a while, and it appears that you've resolved the crashing -- however, I am now seeing very bad mpeg distortion. This isn't my photo, but it is similar in image to what I am seeing.

The distortion begins after about 5 to 8 seconds of high-quality image viewing on the analog channels. The distortion is bad enough to make the content unwatchable. XBMC digital channels are ok, Mythfrontend is ok with analog channels.

The log was very large and wouldn't post to xbmclogs.com so I've posted the first 5000 lines (out of 115k) after beginning to select the channel. I also posted just the lines that had the word "Error" in them into a separate paste file. I'm not sure this enough, if not, let me know what you'd like me to "filter in."

Thanks
Hi, the issue is resolved now. But you have other things not linked with addon. First now disable "extra debug log" to avoid to fill you disk.
Also retry to watch the channel for few minutes and then copy the stream file from mythbackend to your xbmc video folder. Then try to read it using xbmc to see what happend. You can also post the file somewhere, then i can get it to test it. Thanks.

Janbar,

Sorry to take so long -- I had some unrelated XBMC problems. But, I have captured some files from live TV and from pre-scheduled recordings. Both types of files behave the same:

- They are mpeg, even if I uncheck transcoding. I assume this because the capture card is MPEG?
- They play fine in MythFrontend
- They will play fine in XBMC "files mode" as a regular mpeg file
- They will play fine in XBMC MythTV add-on as a "recording"
- They will play in mplayer

- They will not play fine in some other SW -- tested VLC and Movie Player
- They will not play fine in XBMC MythTV add-on in "live TV" mode

This is what mplayer reports about the file:
