I think I got about 10-12 minutes - I caught the first score and then it stopped. There were a few dropouts and hiccups in the preceeding 5 or 6 minutes before it finally stopped recording and then I got the problem message.
I have had my XL for over 2 years now and I don't remember this happening before. It used to happen all the time with my Comcast DVR.
I guess it was a local issue since you guys had the same thing happen but it is weird that it wouldn't continue to record. Hopefully it was just an isolated incident.
