I used to have Media centre XP 2005 which worked but then when I disconnected and re-connected the computer it does not work. However the card does work if I use the Hauppauge driver (V6) and their software. 1. media Centre claims to be getting no signal whereas there is a good signal on all channels (5 antenna and 1 cable/set-top box) 2. I cannot download the upgrades (rollup 2 onward to October 2006 as they are no longer on the MS site (though they say they are). Why? None of this particularly worries me save for the timed recording feature in media centre which is quite useful. Any help appreciated so long as it is not so technical I willl not understand it (e.g. registry fixes, etc) thechandra
