I'm having a bit of a problem with this tuner. When I go through TV setup, Media Center will find the tuner and tell me it's supported but won't be configured (doesn't tell me why - not very helpful). I have added the software that comes with the CD to be able to use it with Media Center and also increased my tuner limit to 8 via tunersalad, just in case (as I already have two PCI tuners, a single one for satellite, which receives HD, and a single card with two tuners). I thought the card was being picky with my signal so I bought a new booster and spent ages fiddling with the aerial yesterday but to no avail. To double check it wasn't the signal, I installed the PCTV software and it found about 108 channels (all SD at 100%, HD at 49% - but they play fine). It is really annoying. Anybody have any ideas?
