If you are using MythTV to record, just do a lossless transcode, or use mythtranscode with the --mpeg2 option. Otherwise, ffmpeg -i infile.mpg -acodec copy -vcodec copy outfile.mpg should do it. signature.asc Description: PGP signature

How can I do that? Thank you very much for any help in advance! Have a nice weekend! Best regards, mcc My advice: Mux it into a different container. TS is meant for streaming over lossy networks and has a pretty high overhead. I don't have a TS file ready for some testing but even the simpler PS has in my test 4% more size than the equivalent MKV file. For TS I guess it is more in the 5-6% range.

What you've just described is reencoding, even if it's from a TS with multiple subchannels, 4 different audio tracks, and a week of program info in PSIP to a single-channel TS. The fact that the output container is similar to the input container is irrelavant. It's still reencoding. -- Walter Dnes waltd...@waltdnes.org

Re encoding is when you actually change something, like audio or video codec.
