Picture quality is not as bad as many say. I have not had the service for more than a few days, but this is how it seems to me: (Compression seems to be less than my locals)
5738 KTVU/2 FOX - Color Good, Sound OK, Some Ghosting
5737 WAGU/5 FOX - Outstanding Picture, Great Sound, Slightly Better PQ Than My Local.
5736 KGO/7 ABC - Color Ok, Sound OK, Some Ghosting
5735 WSB/2 ABC - Great Picture, Great Sound, Much Better PQ Than My Local Which Has Terrible Ghosting.
5734 KPIX/5 CBS - Color Good, Sound Good, Slightly More Ghosting Than KTVU & KGO.
5733 WGCL/46 CBS - Color Good, Sound Terrible With A Tinny Sound & Too Loud, Better PQ Than My Local Which Almost Bleeds With Too Much Color.
5732 KNTV/11 NBC - Color OK, Sound OK, Picture Sometimes Looks A Little Deep Fringe (If it is uplinked in SF & Received VIA OTA From San Jose That May Be The Reason).
5731 WXIA/11 NBC - Color Great, Sound Great, About Equal PQ Of Local.
All in all I am happy with this service which will only get better with addition of the fiber optics to the uplink.
