red/pink pixels flash on screen when wathing recorded tv

Help please.
I recently installed a Hauppauge WinTV HVR 2250 on my new Vista 64 bit machine and began using Media Center right away. But after my 3rd TV recording I'm starting to see flashes of red/pink pixels during playback. The dvr-ms files also crash my Windows Media Player but play fine in VLC Media Player. I've tried unistalling and re-installed all kinds of codecs but nothing is working.

Can anyone help with this?
