Hi, new member here!
And also new owner of the HDPVR 630 (for about 2 weeks, received it in late August)
After 2 weeks of use, I have to say, this receiver is a dissapointment. The 3-second lag before the Guide screen comes on and the random crashes/reset. Not to mention the fact that there is no actual button on the remote to switch between your favorites; everytime you want to do that, you need to do this annoying multi-button combo on your remote: FAV button--> scroll and select your desired favorite list --> ENTER button -->BACK button
What a pain in the ass. And this is when the receiver actually responds to the commands because most of the time it doesn't.
The HDMI output really makes a difference as far as image quality but navigating through the system is really not fun.
I really hope they address these issues with the next update...
