I'm using DreamTV 0.49, you need to install tuxvision & trex first.
The image is OK! blanks out from time to time (I think when it lose sync), this is with a wireless PC (802.11b) 11mpbs & when doing some work in the background - 100mbps connected PC appear fine - but i've had limited tests ao far!.
At this stage I've not worked out how to change channels remotely, plus only one PC can access.
