[mythtv-users] Is anyone else having problems with lossless MPEG-2 TS transcoding?

[Scott Alfter]

Lately, I've had problems using MythTV's built-in lossless transcoding with 
programs that were recorded as MPEG-2 transport streams.  I first ran into this 
with Carrier (recorded in 1080i from an A180)...there seemingly was no audio, 
but I think the video was OK.  I think the local PBS station puts out multiple 
audio streams, and the transcoder picked the wrong one.  More recently, my 
Battlestar Galactica edits (recorded in 480i over FireWire from a 3250HD) were 
more badly corrupted...video frames appeared out-of-order, and seeking within 
the file didn't work.  I didn't have this problem with transcodes of season 3 
episodes made with older versions of MythTV.

I've replaced BSG with files from...um...other sources. :-) I could make 
before-and-after samples of the next episode available once it airs later this 
week.  I'm running 0.21 build 17100 (the newest Gentoo ebuild as of a week or 
two ago) on AMD64 Gentoo.  (If it matters, the underlying system uses a 
Gigabyte 945P-DS3, a Core 2 Duo E6300, and a no-name PCI Express FireWire card 
with a TI chipset.)
