I am upgrading my old setup of a HD40a and set top box. I have been debating whether to go with a Sony 250GB HDD SVRHD900 or to invest in a HTPC with twin digital tuner instead. There is a $100 difference in it, and the computer would have 50GB less storage. The reason I am wondering is the computer route offers me the opportunity to upgrade components myself at small cost, where as the Sony I am dedicated to their update schedules if any, and cannot upgrade components. However, I have already converted my main computer into a HD TV recorder - dropped a card in and increased RAM and HDD size. This is fine and works well except I get a lot of pixelation from time to time - which I am blaming on the long extension on the aerial. As we are renting until our new home is built I was not going to bother too much with the aerial until we got into the new house. Anyone got any thoughts?
