I've looked through these tools a bit, and from what I recall, split_mpg produces broken results. Also, I've found GOPchop to be a bit broken, and apparently dead, but 'gopdit' seems to have replaced it as a useful barebones util.
I am trying to split a 6GB nuv file recorded with my DVB card into chunks small enough to fit onto DVD, however am not having any luck. I tried "dvb-split_mpg filename.nuv 1000", but it just returned the usage information:
"usage: split_mpg <filename> <size>"
Which is what I typed!
I then tried to use GOPchop, but when loading a nuv file recorded with my DVB card into Gopchop 1.13 I get the following errors:
parse_MPEG2_program_stream @ 0(0.00%): expecting pack_start_code, got 0x00 0x00 0x01 0xE0

Is it possible you have a Transport Stream (TS) rather than a Program Stream (PS)? I don't know anything about DVB captures, but I know a lot of MPEG utils won't deal with TS's. Maybe 'replex' or 'dvb-mplex' will demux it to a PS if that's the case. You may even be able to remove some streams you don't want from the capture to reduce the size.
