The card was working on old PC (3.0 GHz Pentium 4). I swopped the motherboard and added an E6600 CPU with a Westchester Intel mboard and Sparkle GEFORCE 8600GT card.
Memory leak problem occurred and I've tried to use the new TVR application (TVR 18.104.22.1680) and drivers (22.214.171.124). BUT, when using the TVR 126.96.36.1990 application the onscreen items are labelled with weird characters, for example: TVAir = Àíòåííà. These settings are seen in all the Panel configuration settings files.
The PC crashes with a blue screen when you reboot after installing files.
During startup of the TVR programme this error appear continuously: error 80040212: cannot run preview graph. Looks like memory leak problem won't go away with the new app and drivers. I'm suing the same version of Windows XP Home (service pack 2 is included) and Direct X v 9.0c
