#12533 closed Bug Report - Crash (Unverified)

mythtranscode crash when transcoding .ts files recorded with Hauppauge hvr-1600 (us hd cable)

Did a pastebin of the output from mythtranscode

This only seems to happen when transcoding video files that have a .ts extension. I have tried both with and without cutlists and that makes no difference. Transcode of .mpg files (the very few that there are) work correctly.

Recordings were made from a Hauppauge HVR-1600 capture card on MythTV 0.28

mythfrontend --version shows:

The following is the output from the Ubuntu crash report I got:
