I ditched my HD1000 and went to a modded Xbox and have never looked back. But if HD is important to you then this isn't an option. I realize that most of the HD1000 users used it due to it's HD functionality.
Mebby I did the same thing, pretty happy with the XBOX 360 as my media player although no VOB playback, just dealing with WMV and going old skool with a DVD player until a better piece of hardware comes along.
I too have a HD1000 Rev.A w/compact flash card ready for eBay, it has a rewired PSU, but something else has caused the Roku to stop working. I've had enuff though, so if anyone would like to contact me about it, please do.
Good riddance ROKU.
