I am testing DVDFab Platinum (currently 184.108.40.206) and I like it in many respects.
The ability to hard code subtitles is great for my Archos and the flexibilty to either do 1 or 2 passes gives me the options of speed or good quality.
However I am testing the H264 Generic mode and find it works very well for the video, but that the bandwidth of the AAC audio track (tested at both 32 and 64KBits) seems severly limited. The upper frequencies seem absent.
I am comparing it with the DivX MP3 conversion (at 96KBits audio) which seems very much better.
I am playing back on Nero Showtime and the Archos 504 which both give identical results.
Is there any technical reasons for this - what is the sampling rate of the AAC?
