I made an mpeg2 file using ffmpegx and used vcd tools to create xa images and burned an SVCD using toast. It plays fine on my computer but no sound. I burned this same mpeg2 file as VCD and everything looks fine but of course the resolution is lower.

The only thing I can think of is that the audio was encoded at 48 khz but that seems to be in spec.

Does anyone have any ideas?
