Since L655, I have had the following issues:
The TV1 remote works well sometimes but other times, 1 press = 2 and sometimes nothing happens at all.
The day after I got L655, I bought and hooked up a Western Digital My Book 500gb EHD. I transferred programs over with no problem. But when I went to play one, it played fine, but the receiver would not respond to the remote or front panel buttons. I couldn't skip forward, backward or even stop. I had to do a red button reboot. When it came back, I tried to play a program again on the EHD, and buttons worked for about 2 minutes until it locked up again. I rebooted once more and tried it again and it then worked fine.
I went to Dish Home Ch 100 a couple of days ago and it will sometimes have the pillar bars flashing colors unless I have the gray bars up. And occasionally also the entire image is skewed down about an inch causing the crawl at the bottom of the screen to be below the bottom of the screen. The yellow frame that circles the individual channels however were positioned properly (skewed above the channels being selected). This has happened a few times.
I was browsing and then downloading a program off of Dish Online. When I went to exit by clicking "done" the 722k froze up completely and then rebooted on its own. When it came back up, I went to play a recorded program when it froze up again and rebooted as before. After that, it worked as it should.
