if you don't identify the input as an mpeg2 (with -x) transcode has problems.
heres what i use:
transcode -i /var/video/1070_20030827013000_20030827020000.nuv -x mpeg2 -V
-y mpeg -F s,2 -J skip="17474-22934 45074-53850" -E 44100 -b 128 -o

tcmplex -o jupiter-jazz.mpg -i jupiter-jazz.m2v -p jupiter-jazz.mpa -m s
