Is this just a known issue for hardware-MPEG2-card recorded streams,
or all MPEG2 streams in general? I regularly record DVB and PVR-350
streams here in the UK, demux them, edit them, and then burn to DVD
with no issues at all (using Project X (Java) to demux and fix,
Cuttermaran to edit [uses mplex], and then DVD Hive [uses dvdauthor,
mplex, and mkisofs] to create ISO images). I sometimes also reencode
edited MPEG2 streams that have been through the demux/remux process
into XVID/DIV5 with no A/V sync problems.
Does this problem affect all popular linux-based tools mentioned in
this thread? I use the above tools on my Win2K box because they are
all GUI-driven and, having not tried other tools and because they
worked, have not looked at others. It'd sure be good to be able to do
it all driven from a GUI on my myth box from the sofa!
