I have an old TX-20 on one TV that also has 2 Series 2 DT's. The TX-20 was so slow to do anything that I really only used it for playing DVD's. Finally, it got so slow that I had to reboot every time I wanted to watch a DVD so I finally got a new hard drive for it from WeaKnees. It took 10 minutes to install and now the thing is as zippy as either one of my Series 2 DT's! It's got a whole new life. $109. total. I shudda done it months ago.
