Hi All, Due to a disk failure I've just rebuilt everything and have been playing with all the latest codecs out there. I've encoded some material I collected from DVB using transcode into MPEG-4 using XVid and Vorbis. There are two ways I can merge the audio and video files into one complete files: ogmmerge to produce an OGM and mkvmerge to produce an MKV. I notice that when I play the .MKV file back I have to give a -delay -0.3 to get the A/V correct. I do NOT need to do this with the .OGM file. Any idea what is going on here? MPlayer is using the same backends (xv and oss) for output and I can't see how the packaging should be affecting it. Any ideas?

I saw this the first time I made an mkv but never have since. Do you have the latest mkvtools? You can specify a delay when you use mkvmerge so it plays correctly. Martin

I'm using the latest mkvtools (v1.0.1 ('October Road')).

Now that's interesting. But why would transcode (or anything else) put them NOT in synchronisation? Now, maybe the TV station transmits video a little offset from audio so that there's time for the decoder to sort it all out. I wonder if transcode gets the resynched correctly. Any ideas anyone?
