Too bad your experience is dead wrong. Computers, of all devices, probably render the DVDs the best, because it's a direct digital display. Not only that, but PCs have the best quality scaling available, which far exceeds the abilities of your average upconverting DVD player.
All in all, the PC is going to provide a far better display than your HDTV system will.
But this isn't what you originally claimed. You claimed that the difference between bluray and DVD wasn't something to get excited about. Which you'd have to be nearly blind to not see. I can understand not wanting to shell out for the rather expensive players, but not wanting one at all ever?
For someone who doesn't care about the difference between DVD and bluray, you sure get uppity about this. Besides, nearly every game out there doesn't run in 1080p, nor does DVD look any better upscaled. If he's using component he's not really losing anything, assuming his TV supports 720p/1080i.
Also, many Pros now come with HDMI.
You do realize the jump from SD programming to HD programming is nearly the same as bluray?
You have: 480i -> 1080i for SD -> HD programming
You have: 480p -> 1080p/1080i for DVD -> Bluray
