Up until a little while ago, I had no problem playing MPEG2 files on my system.

Now, almost none of the MPEGS originally rendered by Vegas or TMPEG seem to play properly. I've tried uninstalling quite a number of apps and I can see Media Player is uising a different decoder after each layer of the "onion" is peeled back but I'd really like to ensure that the Mainconcept decoder is used -- is there a way to adjust the priority?

Whole portions of rendered files are just staying black or audio is stuttering...

Thanks in advance for any suggestions,

Jonathan
