DVR recording issue - DirecTV

I am having my DVR recording problem in past 3 months and I called the technical support 800 number 3 times but the issue keeps coming back. I even followed the troubleshooting process in the channel 411 almost every few days but the issue is still exist.
The issue is that I could not record and playback the program at all or sometimes it could only recorded part of the program and then stopped.
Any suggestion?
