i was at xbox-scene and i saw an add for this dreamx thing.it is an xbox with a 1.48 ghz tuatilon and 128mb ram. so basicly it just doubled your cpu power /cache/ aswell as doubled your ram. it also has a modchip in it and a pre installed on/off switch. you can kick the speed down to 740 mhz if you need aswell. They also add optical digital sound out and s-video biult into the box,you can upgrade the hdd just like any other modded xbox also. this makes the xbox look so much better. some poeple have reported that when they run mythtv on an xbox that it sometime has a slight delay, well with this then its no problem.one problem i have is that my receiver is a 6.1 channel decoder. will it decode the 5.1 dolby digital?
