If I remember to do this tonight, I will and will post tomorrow. But have out of town guests showing up in a little while and don't know if I'll be messing with TV later or not.
Out of curiosity, how about a little info about your system. What model DVR, what type of dish, SWM or conventional, etc.? Do you have more than one DVR and does this happen on both/all?
Replicating the problem would be more likely and relevant if done on the same type of equipment.
