I've had my ViP622 since April. There was a few things the installer didn't set up correctly, but I'm pretty good at following instruction manuals. Since then it has performed flawlessly. Well, you have to unplug it from the wall once in a great while when it gets stuck and just sits there. The software upgrades it installs at night have made it more fault resistant. I think mine is the B revision too. An early mainboard, but like I said, I am very happy with its performance. It runs real hot, especially in the summer. About 128 degrees Fahrenheit on average. Which brings me to my question. Has anyone tried swapping out their hard drive for one with more capacity? I've never opened mine up, but I was able to ascertain that it uses a SATA hard drive. Donno whether it's SATA I or SATA II. It's either 250 Gb or 320 Gb. I guess the thing to do is try it. Someone said the ViP622 will download the operating system onto a blank drive from the satellite. I'm not usually a pioneer on things like this as long as it's working correctly. Keep waiting for that hard drive to burn up so I'll have just cause, but I would like more than 30 hours HD recording time. Sorry if this has been addressed on another thread. The search terms are so generic, "upgrade vip622 hard drive", "increase hard drive capacity vip622", etc., that I have a difficult time returning useful search results. But I'm a noob on this forum. Thanks in advance.
