OK, Im trying to convert my Xvid file to MPEG and Im having a few troubles. The why that thought would be best would be to use TPMGEnc but there was no audio in the output file. So then I thought about using virtualdub to extract the audio first. This presented a new problem. I get the error message "The requested audio compression is not compatible with the input format. check that the sampling rate and and channel count match those of the requested format" I find this a bit strange as I've selected no change from the input file to the output. I suspect that this is codec related but I have the Xvid codec and the films play fine in WMP. Anyone got any ideas?
