I created the m2v and mpa files using Premiere 6.5's MPEG Exporter. Bring the m2v file into DVDMF2, video previews fine but no sound. OK, try Replace Audio, select the appropriate mpa file, error message says "No Audio Data". The same thing happens using the mpa files provided with DVDMF2 as background tracks.

The mpa file plays fine in Media Player, and if instead of producing two files, I export a multiplexed mpg file from Premiere, all is fine in Moviefactory.

Any ideas what is causing this? If not, is there any real difference in quality between using m2v+mpa or muxed mpg files?

Thanks in advance.
