Yes, I'd thought that, but a straight drag'n'drop to an XP box, rename and
play, and WMP doesn't recognise it. Most likely my recording profile is to
blame - are there any settings specific to making a DVD-compatible file
that I maybe am misunderstanding, do you think?

Yeah, I had planned to just remove the adverts and trim the start/ends
before burning - and much as I appreciate Myth has the cutlist to do this,
I find the editing is done so much easier in a GUI package - like yourself
I'll fiddle with nuvexport anyway - I'm sure it's maybe doing more
"transcoding" than it needs to - ie. just demuxing. Failing that, it must
be the recording profile settings. The cards are, as you say, DVB-T cards
so output a raw MPEG2 stream anyway.
