"converting 25 to 24 is not the best of ideas."
not the best of ideas,damn I must have been doing all my stuff wrong then LOL.
I use avisynth for all this stuff,and I have NEVER had a problem yet converting ANY of my Retail PAL DVD's,I just use these commands in avisynth:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
MPEG2Source("C:\Whatever\whatever.d2v")
AssumeFPS(23.976)
spline36Resize(720, 480)
among other filters I decide to use depending on what I am doing,and I get my .d2v files from DGIndex,it will also tell you the delay in the .ac3 file if any.
and I have not had ANY problems yet to date converting the sound either,just sometimes occasional lower volume,but still works fine.
If the sound is only DD 2.0 you can convert to PCM and normalise to get a overall boost and then remake your .ac3 file from that,which also works just fine,I have converted a ton of DVD's and doing some right now as I type.
So if there are better methods,I would love to hear them,but for now this method works great for me.
I have gotten these methods from Citizen and Moth3r at OT,and everyone knows(pretty sure everyone knows)how well Citizens SW sets and Moth3rs SW sets turned out.
1 thing you might want to check though is after you make your avisynth script you want to test it first,for any wierd interlace problems,I have only found wierd problems sometimes with downloaded avi's from the Internet,I have not found ANY with retail PAL DVD's(knock on wood) so far.
but what I do to check is load your avisynth script in VirtualDub MPEG2 and then step it forward frame by frame with the keys buttons,and look for any problems,also you can click on file and then file information and it will tell you that your video in running at 23.976 fps.
hope this helps
like I said I am sure there are waay better tech experts that will say this does not work,but it works for me,and EVERYONE that has had me convert DVD's for them.
