The ideal solution would be to get mythtranscode and mythreplex to work together better on DVB files. The problem with projectX is that it adds at least two extra dependencies which when it was used in MythBurn gave a lot of people problems setting up properly.
Having said that I'm not totally against using ProjectX if it can be made to work. If it can be done so it is optional and doesn't complicate the script top much (I'm the one who will have to maintain this stuff
) then I will consider adding it.
Another chap was looking at doing the same thing but he discovered a problem with ProjectX in that sometimes the audio would dropout part way though a file. Possibly related to having run the file though mythtranscode before using ProjectX on the file. Have you seen anything like this?
Are you using it to cut the commercials or just do the demuxing? How do you handle files with multiple audio streams?
