PS 3 and choice of transcoding setting puzzle.
 

Can't find this problem raised in any Nero forum, so maybe this forum will
help?

To transcode a .wmv file made in PS 3 I have been using the 720x576 PAL
setting, with quite fair results in Nero Vision Express. It suddenly dawned
on me that 768x576 would give me the 4:3 ratio I really want. So I
transcode with this setting, then add the .wmv to Nero Vision Express - which
promptly changes it back to 720x576! Well, the result is still o.k. but I'm
curious about the reason my selection isn't accepted. Is there something else
I should do in PS 3 before adding it to Nero?
