I have a new dvr-320t, and find it great other than when I press record in the program then try and stop the recording it wont let me. It asks if you want to stop recording, I select yes and it continues to record. I've tried stopping it from the play list too, but it still records. The only way to stop it is to pull the power cord out. Does anyone else have a problem like this? Or is there some minimum record time or similar setting?
