The streams I have (from UK DVB-T) are 720x576 PAL with MP2 audio
and a bit rate well under that limit - this is one:

[tcprobe] MPEG packetized elementary stream (PES)
[tcprobe] summary for 3000_20050326172300_20050326175500.nuv, (*) = not default, 0 = not detected

converting to DVD PS form with the relevant sectors for dvdauthor
to insert stuff into.
