Sounds like it's pretty even in the problems department, here is a quote regarding the Fusion
Ive just rebuilt my media PC and finally have live tv actually working but like you I cant get Channel 9 ans SBS. The HD channels are flakey except Channel 7 it works like a dream. The only way I got mine to work was to use the cheap rabbit ears, the antena supplied to the apartment would not give any channels. Im in an apartment complex in Redfern, Sydney.
But then people with the VisionPlus have had similar issues. At least now the manufacturer is working on releasing MCE-compatible drivers.
