Matrox MX02 Mini and FCP 7...

We have been using the MX02 Mini essentially for HD monitoring and have run across a few issues that have hindered productivity. It appears that one or two of these issues have been fixed in the latest 2.2.1 software release. The following remain. Has anyone experienced the same?

1) Audio scrubbing... audio cannot be heard on a per frame basis, usually audio is heard every three
frames or so.
Apparently this has not been fixed.

2) Audio playback. In the viewer... Hit play... Playback begins but the audio drops out and then
resumes... hit stop and playback repeats the last bit of what was playing before you hit stop.

3) Audio distorts, similar to an analog overdrive sound, when hitting play every 10 times or so.

Most of the projects that we are working with are Apple Pro Res 422 @ 23.98, Audio 48khz/16 bits.
Most of our computers are as described... 2 x 2.26GHz Quad Core Mac Pro running 10.6.6 and FCP 7.0.3.
Hard drives are local external 2TB G-RAIDs with plenty of room. We have check all of our media to make sure that it matches our sequence settings.

I realize that there are Matrox advocates out there, but we seem to have a hard time getting the MX02 Minis to work reliably.

All ideas are welcome. Note that we are working with Matrox support as well.

Thanks,

Scott
