It cetainly appears normal that your WMA9Pro program installed its own
decoder when you installed itand therefore will play the clips when you run
However, it appears that when it runs it sets its decoder as the one to use
also for decoding of video from MC TV or DVD. So when you try and play a
MPEG2 encoded TV or a DVD you get the WMA9Pro decoder which of couse can't
decode the Mpeg2 data.
You can use the following 3rd party Vista decoder utility to see what
decoder MC is set to use and you can change it if you like. http://mediacenterexpert.blogspot.co...r-utility.html
