ok, i installed it again with the bdasup.sys in the c:\windows\inf and it went ok, this time WITH the automatic restart. then, when it got to the 'ctrl-alt-del log in' screen i got bsod. after another restart i got into desktop but after launching my tv software (winfast) i again got 'failed to build graph' then i downloaded another program, 'DScaler' which also reported error (can't load hardware driver, possibly caused by corrupt installation. reboot and try again. file c:\source\deintelace\dscalerbuild4115\dscaler\dscaler\providers.ccp line 488). then i downloaded and installed the latest winfast version and it worked, kinda. there was no 'failed to build graph' message, i can get into the setup, choose my country and all, but every time after scanning the channels, the application crashes... can someone tell me how to fix this problem? or maybe you know some other, better application for my leadtek 2000 xp expert tv card? thanks edit: i tried to press 'stop scanning' before it's finished, but that also makes it crash. edit2: i gave up.
