I noticed today that if I go to the sports category via the Roku, all the episodes are listed as only 30 minutes each. If I go through the web or iPad, they show up correctly (like 3 hours for NFL games). That only seems to happen for sports.
I am going to do a test and set it to record the PGA tournament tomorrow. I think it will record the whole thing, since I can see the recording on the iPad for the correct time period, but I want to be sure.
