It could be a coincidence, but I again set the Isles game from last night to transcode (like I've done with all the games this season) and woke up this morning to find it ready to download to my iPad. I've got the whole game and I've been able to watch it (well half of it so far, but I'll finish it on the commute home later). It recorded the TSN feed (ch 771 or 772, I don't know which one). Perhaps its fixed?
I've also noticed that my Genie, since canceling the recording of the Isles v. Coyotes a couple of weeks ago, has taken to recording all feeds of the Islanders at once now. I get home to find three or four recordings of the same game. Ch 635, 771, 772, et al. I'm not complaining, its actually kinda cool to have my pick of feed to watch, and with 5 tuners it never cancels anything else to record all that. Oddly, however, the Genie Go only offers one of those recordings each time, and I don't know which one it is until after it is transcoded.
