I've seen the Teac gear up close and personal although I don't own any. The equipment appears to be very well built and the sound was very decent (I was looking more at the Teac audio stuff).
As for using a computer, personally I wouldn't want to wait for the computer to boot up, look into yet another space consuming CRT monitor to operate the computer, launch the appropriate software, and listen to the computer fan noise in the background just to watch a DVD. Sometimes it makes more sense to buy the standalone "appliance" like an inexpensive DVD player. Good luck.
