I've been watching the Texas Stars games lately. Overall the presentation is good. Cameras are Hi Def, the audio is just the radio feed, so I imagine the audio quality will vary depending on what team you're watching. The Stars' guy is good.
My biggest complaint is with the replays. They will start to show a replay, then when it is about to get to the good part of the replay the video will freeze for a second, then change to another angle. Sometimes you get to see the play from the new angle, sometimes they cut back to the live play. This happens multiple times per game.
At stoppages if they aren't showing a replay they will quite often show the view from the camera way up in the corner. I think they'd be better off to stick with a closer camera than that.
It's really good value IMO. I just subscribed to the last month because of the new additions to the team. Previously I'd used the NCHC app which is by Neulion. The AHL one is way better.
