I tuned to channel 778-1 to watch the Wings/Oiler ADVERTISED HD game on Fox Sports Detroit, only to find the game is NOT in HD...what gives??? This is happening almost nightly.
Lazy me, just tuned to the channel that says HD, and I expected it to be in HD...am I wrong?
Was having the same problem....after reading your post, I called in and did the same thing. Channels seem clear now though tonight's Flyers/Lightning "HD" feed is actually the SD feed. Apparently SUN isn't showing it in HD. That's ok, at least I'm not seeing the 721 msg any more and hopefully won't miss any further HD broadcasts.This just happened to me tonight.. i was getting 721 error on the FSSW HD feed for the Stars game. Also, going through the CI channels, all of the HD feeds were greyed out as if I wasn't authorized for those channels.
i called directv and through the automated service said "message 721", or "extension 721". it then automatically went through and resent authorization and now the HD feed of the stars game is on!!
The CI channel list still has the grayed out entries, but the HD feeds are now coming in. very strange but pretty awesome that the automated phone service was able to fix it!
And sometimes even that doesn't mean anything....see my post above yours. The PHL/TAM HD channel has the HD logo and I guess technically, it's a HD presentation though it's a 4:3 SD image with SUNSPORTS sidebars.Next time look at the tv guide itself and see if the HDTV icon is on the games listing.
