I have a HR20-700 that is really struggling to respond. It often takes numerous button presses to get anything to happen. Scrolling and channel changing is awful. I would really like a new DVR that would perform better but I can't say my current DVR iDisk broken. It's just old and not very responsive. What would be the best way to get a newer model with better performance? Just buy one on my own? Call retention? I have been a D* customer since they first launched however long that is. And what model should I shoot for? I only have 2 TVs and I'm not interested in the whole home set up. So would an HR24 be adequate? Sorry for the basic questions and thanks for any thoughts or advice.
