- From what I can tell from the man page, -af resample will always resample. - -srate will leave a 48kHz stream alone. However, neither option should have any affect on an AC3 stream as long as you use the '-ac hwac3,' option, which will pass the stream unaltered to the spdif output.

Resampling a stream to 48kHz is very trivial in software. Picking the closest IEC958 rate and resampling to that in hardware isn't nearly as trivial. Why make it complicated? Put a CD in your DVD player and play it.
