Hi Gary, I tried the scaler using the DVI passthrough on the Crystalio and the image is not bad at the 720P and 1080i fixed resolutions the Snazio offers.
It appears to be able to do the required stretch by using the Zoom button on the remote. This gives you three choices: actual size, fit to screen and full size (which would eliminate the black bars for you). Best bet is to give the unit a tryout with your Optoma.
SeeMore, the files are those available on the WMVHD website and are trailers.
For some reason the Alexander trailer works perfectly (it says DRM), but the others do not, flagging up a Windows protected content message.
Rob, how does the Snazio obtain the licences for DRM media playback? The licences have been obtained and stored on my PC prior to streaming. According to the Snazio website, the unit should play DRM material.
Other than that, I really can't fault the unit. I use the Wake on LAN feature to wake up my PC and enjoy HD streaming flawlessly. It's played all of the HD content (bar above) seamlessly, even .tp files.
Now, if it could play Quicktime HD, I could watch all of the trailers available at apple's site (I can wish can't I?)
