622 HDMI Compatible with PureAV RazorVision?

[mrhph]

Just had a 622 installed (L.358) yesterday and I have a PureAV Razorvision in between the 622 and the TV HDMI. Occasionally if I turn on TV and 622 I will get snowflakes, and soft reboot won't fix it. To get HDMI port to work, I had to either hard reboot the 622 or unplug and then re-plug the Razorvision. Has anybody had any successful experience with 622 and RazorVision? Just want to know if this is the infamous 622 HDMI problem or a compatibility issue with RazorVision. I have yet to try a direct HDMI connection, but I will do that next. In any case the component output works without any problems.
