i've got the same problem that brad describes: when trying to nuvexport
"MPEG2->MPEG2 cut only" a show i've recorded on my pvr250 (so this is
just simple pal no hdtv) as mpeg2-ps with audio layer2 384kbps nuvexport
is running a while and finally quits with the message:

ERROR: opening A/V streams (0/1)

it might be due the lack of an mp2 file (see bottom of post)

the end of the recording is cut off (as suggested earlier in this
thread) , aswell as the begining. there are no commercial brakes during
that show as you might see from the cutlist.

can anybody help me out with this problem, since editing nuv files in
avidemux by hand is not what i intend when having tools like nuvexport
at hand.

thanks in advance
maestro

here is the complete output from nuvexport:

another question that arises here is:
why is no mp2 file created?
