Hi, I've build an HTPC, running MS XP MCE with all updates on it. The MCE side of it is working fine, couple of niggles but thats not a problem. What is a problem is getting DScaler to work. The Sweetspot card is being fed an RGB signal from Tivo/Freeview/DVD player via a quintro RBG switch box. I've tried DScaler 4.1.7p4, 4.1.8 and 4.1.11 (which says its 4.1.10?). I've tried the WDM drivers, and the BT Wincap drivers (not at the same time obviously!), and I've tried without any drivers. These have been downloaded from the Pixel Magic website so are the latest drivers. If I reboot the machine and install & run DScaler without any drivers it'll work most of the time. Unless I run MCE first, in which case it'll just give me a black screen and "the video thread did not terminate in a timely manner" error. If I use the WDM drivers I get a really poor picture, fuzzy, ghosting, horrible. If I use the BT Wincap drivers I get an image that sometimes doesn't synch properly, the colours are all mixed up, and the picture looks like the brightness is wound right down and the contrast turned right up - again unwatchable. Also if I use either the WDM or BT Wincap drivers, every time I try to change back from the DShow source to the Sweetspot direct source the PC locks up completely. Also if I do manage to get DScaler to give me a good picture, when I exit it and fire up MCE again, any live picture through MCE stutters a lot, the only way to cure this is by rebooting the machine. Anyone got any ideas what I can do? Apart from binning it and looking for another solution When it does work its but more often than not its a big as I have to hit the reset button yet again.
