Well, I don't know too much about MPEGs, streams, formats, containers, codecs, ... - what I do know though is that the tool chain described in my mail hasn't produced broken DVDs in months; omitting the demux/remux steps resulted in unusable DVDs. In fact I'm not sure whether the projectx demuxing step is the "intelligent" one, or whether it's mplex; I suspect the latter, though, and thus I thought it might be a good idea to use (lib)mplex as a muxing backend. I've had a quick look at the sources of libmplex; it should be possible to create an adapter class for dvbcut, altough it will not be as simple as for ffmpeg. > I'm using an authoring tool that does demux and remux > (automatically). Which is...? :) With projectx for demuxing, directly piping its output to another muxer is not possible, as it postprocesses the files it writes. > Conclusion: An additional demux/remux step will probably make > dvdauthor shut up, but it doesn't actually repair anything.

VDR (for some reason) is not able to produce files larger than 2 GB (missing LFS support?). Recordings of films result in a set of 2 GB files (had a /long/ film over easter with a high bit rate that resulted in 5 chunks...). Omitting the "cat" step would be great :) Best, Bastian -- Bastian Friedrich [EMAIL PROTECTED] Adress & Fon available on my HP http://www.bastian-friedrich.de/ \~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ \ Half of the people in the world are below average.
