Hi there i have a haupauge tv tuner card and for some reason it now is showing wavy lines in the picture. Im wondering if anyone has any idead on how to fix this? Thanks in advance for your help

I have also posted an example of what im talking about.

 

mr friend had some similar troubles with his Happauge as well. Driver installation can be tricky with tv tuners.

have you tried the latest drivers from the happauge site?

I have instaled it corectly and it has worked fine, it has just started doing this. I trie reinstallling the drivers last night , i didnt however del the old ones first because as you say installing can be tricky. Any ideas?
