So, okay, after goofing around with multiple MCE boxes on different TVs, copying data back and forth, ladida, I finally realize, hey, this should be a lot easier.
And it is. Media Center Extenders.
I have since retired all but one media center box from service, and placed extenders on my other TVs. I chose the XBOX route (Media Center Extender for XBOX), as the included remote control and dongle also double as a DVD playback kit. And System Link Gaming capabilities is always a cool thing.
I combined my storage to a single large volume. The box doubles as my main MCE box, with extenders connecting to it. Four 200GB IDE drives, off a Promise FastTrack TX4000 Raid Controller (each IDE drive has it's own dedicated channel), and striped (no parity). 800GB of storage. Finally, a worthy repository.
How soon can I fill it? And when i do, will I be satisfied?
