I recently received two new 830's to replace my 630's. Other than the usual complaint about no front displays (I bought a small clock to sit on top of the 830), I recorded two shows at the same time yesterday. Both shows stopped recording for 2 minutes at 5:30 eastern and then started recording again. Is there a reason for this? Also, when I stop watching an in progress recorded show, I'm asked whether I want to stop recording this show. Is there a way to turn this notification off?
