Just had a 'Stop D1' today on my Win7 64bit system and it said hcw89.sys was the culprit. Thus is a hauppauge driver file.
My HVR2200 driver is vers 28162 from June last year and is the latest.
Google shows I am not alone but the reports seem to be for a couple of years ago.
Peculiar that this is the only one I've had as I have had the HVR2200 for a couple of years.
Anyone else seen this??
