I have been using Matrox RTX.10 with Adobe Premiere 6.5 fine for months. After trying to tweak audio settings (topic for a different post as to why) Premiere wouldn't capture analog video/audio. It does the following.

1) It tells me I must run Audio Capture Drift Detection.
2) When I try that I get a Matrox error message "Unable to create capture buffer" in a window labeled rm-MtxRT.
3) Finally the system hangs and it tries to helpfully notify our friends at Microsoft.

I tried to get around it by (1) recreating the Preferences file, and (2) running the drift test in Matrox Media Tools. Not luck with the first, and Media Tools had the same errors/crash as Premiere.

I reinstalled Media Tools but no luck. Now I can't capture analog video/audio at all.

Any help would be appreciated.
