Audio quality when syncing with video

[Woodlake]

I need opinions and arguements as to which way I should go about syncing video and audio to achieve the best QUALITY.
This is the situation I have;

I have video encoded at 24.996fps (PAL) and audio at 48kHz (both are perfectly in sync). I want to encode the video to DVD, so I need both 25fps AND audio at 48kHz - here are my two choices as I see them;

Encode the video using CCE (which accepts the 24.996fps and encodes it at 25fps) and stretch the audio by 99.984% (using Wavelab highest quality) to match OR

2. Frameserve using Avisynth's AssumeFPS(25,true) and then RESAMPLE the audio [again using Wavelab (resample 192 plugin)]

I am aware that option 2 will introduce a slight change in pitch - but at such small amounts I'm not too worried about it.
What do other members here do - I'm sure this is quite a common occurance? Any comments would be very welcome...

i would do number 2. The change in pitch is so small (< 0.1% of a tone-distance in western music), that it is unnoticeable. Stretching algorithms are not worth it IMO, they can do more harm than good.

co-incidentally someone did a small test about this stretching: look here (http://forum.doom9.org/showthread.php?s=&threadid=76376)

but I would definitely go for speeding up the sound.

Thanks Stephan,

I was leaning that way myself - just thought it would be nice to have some other people opinions too. Anyone else?

Ps I did read that post - it was part of the reason I posted - the framerate was exactly what I have (24.996) and as you have said, I would lean towards resampling rather than stretching - it made me wonder what other members do...
