Pinnacle has released their updated software and drivers for the PCTV HD card (800i), including the long awaited Clear QAM drivers (out of beta).

That said, I tried the drivers, and it did nothing for VMC. In fact, it messed up my drivers so much that a restore didn't even fix it. What happened was it basically took away the ability to view digital OTA in VMC and brought in analog OTA. I had to completely reinstall Vista just to bring back functionality to VMC. This is of course just me, but I would highly advise others, who have the card working in VMC, to not try these drivers and wait for another release.
Anybody else try the drivers yet?
