Everytime i try to scan for channels, it scans a few and then my whole pc crashes, i cant resume operation unless i restart my PC manually. What could possibly be wrong?
As a start, crashes bad enough to lock up the PC are usually hardware or driver related - are your TV card drivers the latest, and are they Vista compatible ?
Click on the 'User CP' link at the top of this page, then 'Edit System Specification' and fill out your system specs - then other users can click on the 'My System' link and see what hardware/software you have - i.e. help people to help you....
My guess is that if Vista Media Center can't see the tuner then MediaPortal may have problems too - does the tuner work with the software that came with it ?
