Until yesterday, I could load an .avi file directly into Vegas with no problems. I installed a video card (mVidia FX 5200) and now only the audio will load. No video from ,avi files. I have downloaded the latest drivers for this card but no joy.

I also have some time ago installed the Morgan M-JPEG Codec 3.0.0.9 that was supposed to cure this problem. (as I recall) I checked to make sure it was enabled, and it was. I could convert the .avi files to something else first but that is another step in the process and probably cost something in quality as well as time.

Has anyone seen this kind of thing before? Personally, I am stumped again!
