Rudy, i think your NetFlix streaming quality might be linked to the fact that you are still using your 1200 baud modem from your days playing Neverwinter Nights on PRODIGY!
Dude! Upgrade your hardware and I am pretty sure your quality will improve.
But seriously, my computer that is linked wirelessly to my cable modem connection gives me crystal clear quality. Not HD or any of that garbage, but good enough for watching surf videos and MI-5.
