Quite a large card, full height and reasonably long (prelude, xsonar d2x size) so space is likely an issue for some. Card failed to be detected twice during installation, proper seating/alignment of the card is suspect here.
For vista, ignore the disc and the 32bit vista drivers from the pinnacle site. Vista will identify the card correctly and will download a later version than is indicated on the site. Since I'm not running 64, I can't tell if these are also available. Appears as Dvb-S is not available in VMC, so an external App will be required. Scanning appears faster than the Blackgold although far less accurate in VMC, certainly in my case and took numerous attempts to find all 72 channels.
Dvb-T quality seems fine, signal strength tests indicate it is probably more sensitive than the BG however quality appears similar, although channel selection seems slower. Has successfully resumed from S3 sleep and both channels were available. Further testing however has indicated that it is at least equal or less reliable than BG, hardware disappeared from resume and failed to be rediscovered after reboot. This maybe down to suspect seating/alignment, however the BG has always been discovered on a cold boot and usually with at least one tuner is available.
Under XP this card maybe provide a different experience, however under Vista it has less functionality, is more problematic installing and has proved at least as unreliable if not more so than the BG. Not recommended, failed experiment, BG reinstalled.
Hope others have more luck...
