Capturing from TV decoder/PVR with Pinnacle Studio 14 / 510 USB card gives vertical lines throughout the whole of the video, using 32 bit Windows 7. I have a Radeon HD 6870 videocard with latest driver, capturing to internal HD. My old Win XP computer with Pinnacle Studio 10.8/ 500 PCI capture card give excellent result from same capture source, even when capturing to external HD.
What can I do to get the same perfect result from my new investment?
