Need more info. What kind of signal? Is it split? Are live tv and recordings poor or is it just one or the other? Etc...
I've been using a 500 for about the last two weeks with Meedio. At first I was pretty ticked because my picture quality was terrible. Over time though by reading posts on various other forums aimed towards the WinTV cards I got it cleared up quite a bit. I'm running just basic cable with no set top box and have the signal split 3 times. One goes straight to the TV (so I can watch my broadcast HD programs), other goes to my modem, and last one goes to the 500 card. I'm running the DVI-HDMI out of a 6600gt into the TV.
A few things I've tried (not sure which helped the most because I did them all at the same time)
Newest drivers for video card
Newest drivers for PVR card
Download the Tweak Tool and fine tune the PVR card (this seemed to help quite a bit)
Try not to split the signal if possible
A few people reported they had to RMA the 500 because of a bad connection for the input cable. I know on mine when I first hooked it up Fox was clear and ABC was nothing but snow. I jiggled the cable on the card and it cleared up ABC; no idea why it only happened to that one channel. As it stands now after some tweaking the picture quality is ALMOST as good as watching regular tv. Recordings still leave a bit to be desired but the quality is still better than VHS.
I searched the forums at these two sites (geared towards the Hauppauge cards) and found a great deal of information along with the tools you need to tweak the 500 card.
