I installed the modified WMVRecompress program on another XP machine and
again get the audio codec not found error when copying a file with a
lossless audio track. So that would seem to mean that the problem is
not the setup of my development machine.
So for some reason the Encoder can create a file with a lossless audio
track but a program using the latest SDK cannot re-encode that file
using the same profile. Seems to me that something fundamental is broken.
Any help would be appreciated.
