I have a Formac StudioTVR hooked up to my older iMac. When I watch the live TV video stream, the picture is fuzzy. The quality varies by channel, but none are great. I was expecting a sharp picture that is at least as good as the picture on my 10 year old TV. The signal strength from the cable outlet appears to be fine. I have tried adjusting the frequency for individual channels and it doesn't make a difference. Is this a connection issue or are my expectations higher than they should be. Since this is a live feed, I expected the quality would be very good. My connection works through a good quality splitter, but it is not preceeded by anything other than a surge protector. The TV picture is fine. I also have internet access via cable and VOIP telephone service. I don't think any of that should matter, though. Any insight or comments as to what my expectations on the picture quality should be would be welcomed.
