Can someone please point me in the right direction for a guide on upgrading my box? I have a Philips HDR312 Series 1 (I think) box w/ Lifetime sub. Recently the picture has been freezing/ restarting while the drive has been making a cricket-like sound. I have a new Western Digital 250GB drive available to install. Is there a sticky guide around that can assist me in my endeavor? While I'm at it, I am also interested in adding network capabilities to my unit. Any help would be appreciated. Thanks in advance.
