I'm considering taking the plunge into HD with a PCHD5500. Iwould like to hear of anyone's experience using comcast in Atlanta (or more specifically Dallas,GA) with this card. Which if any channels will it receive via cable? -- ,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸, RichardBronosky ,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,
