Texasbrit, sportman has the crazy idea that this update will allow games to come through on out of market RSNs, there is a locked thread a little bit back if you haven't seen it. He was trying to watch the Phillies - Braves game on FS South but got the 721 message and somehow thinks that the software update will fix that. Since he's from PA, I assume he's wanting to watch the Phillies and doesn't understand that you can't on Directv, except on local Fox or ESPN Sunday Night.
The 721 message comes up when you are trying to watch a package you're not subsribed to. MLB (and NBA, NFL, MLS, NHL, some NCAA) games that are in special packages (MLB Extra Innings, etc) will give this error on RSN channels when you have the Sports Pack because you're not subscribed to the games. Even if you have MLB Extra Innings in Phillies territory, you can't watch the Braves feed of it. He MIGHT be able to watch the game tonight on MASN, if MASN is in his zip code. He said is zip code is 19454, which doesn't yield any results on the Directv RSN lookup.
You can get the sports pack (which I think Sportman must have, or a premier package preview) but the 721 message will appear almost always for out of market games. You can watch the pregame shows and most other shows on the RSN channels but you can't watch the actual games.
Sportman, read this post before you comment again. You can't watch the Phillies (or 76ers, Union, or Flyers) on Directv.
