So for now you're determining that value sort of experimentally? >> I'm also working on such >> kind of scripts right now, because I want to remux especially HD >> recordings to MKV.

Yes, I'm demuxing all the 000xy.ts files in all their component streams with ffmpeg for now first, then multiplex the ones I want with mkvmerge. I might switch to tsMuxeR, maybe also convert back to cleaned-up TS from MKV also with tsMuxeR to make the smaller recording again playable by VDR (I've read in the vdr-portal.de forum some users already experimented with this). >> My problem is still A/V sync, >> all the original TS chunks (I also record into 200MB pieces, because of >> fast editing in VDR) show video delays for each audio track of over 1 >> second, which is also very noticeable ion the final converted MKV.

By "simplified" you mean the merged ts? Lucian _______________________________________________ vdr mailing list email@example.com http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
