No problems for the first 18 months. Problem started about 6-8 weeks ago. This is hard to describe and I hope this makes sense. I have a timer to record all new Nascar Racing events for both ESPN and SPEED channels. The live race airs on ESPN. SPEED re-broadcasts the race a few days later. The 722 is skipping the live ESPN airing as a "duplicate event" and the SPEED timer is active (say 2 days later). I check the schedule, see the problem, and "restore" the ESPN event. After the daily DVR update the timers are again switched. This is driving me nuts and I'd appreciate any help. I've had no other problems with the 722. I use it a lot and love it.
