Trying to get the skinny on upscalers and viewing programs in 1080p. A friend said he was in an electronics store and talked to a salesperson who said the feed to all the HD displays in the store comes a computer hard drive that sends the data to a software based upscaler made my microsoft that upscales the signal to 1080p. I'm thinking my friend is a bit confused as I have searched and found nothing on any software based upscaler made by microsoft. Next, how much do I need to spend in order to watch 1080p programming that has been upscaled. These upscalers, what kinds of programming do they upscale, DVD's, regular television broadcasts? Thanks for any info in this.
