Disclaimer: I've not used the output from a PVR-350 for this
but I have used mpeg2 streams from several other sources.

That seems a bit heavy handed - you should be able to generate DVD
compliant VOBs from random mpeg2 streams by splitting the stream with
mpeg2desc (I use mpeg2desc -a 0 -o audio -v 0 -o video >/dev/null) and
remultimplexing with tcmplex (tcmplex -m d -o $name.vob -i video -p audio).
You get mpeg2desc from the dvddauthor port and tcmplex from the transcode
Don't try and use FIFOs between mpeg2desc and tcmplex, it doesn't
work. Fifos seem to work with mplex but often (IME) generate broken VOBs :(

This is probably necessary, I suspect that the output from the
PVR-350 lacks the DVD NAV (VOBU) packets required by dvdauthor (and DVDs).
