Query: Disappointed

The model of PCTV HD pro stick that I received, was an early model that had software compatible with XP. Since my computer is a very recent model, equipped with Vista, I downloaded the latest software on line to try and operate the device. Even with a series of on line helps from the manufacturer, I was unable to obtain HD, and the standard TV image was shaky and not very clear. I decided to just lump it, and return the item to the seller. I haven't heard from him, and don't expect a refund at this time. I was just glad to get rid of something that wasted my time trying to get it set up. I'm perfectly happy to get my HD TV the normal way, from a new HD television set.
