Gizmodo has a guide, "Ten Things You Should Consider Before Buying an Upscaling DVD player; here are some of the highlights:
• Does it upscale to 1080p? Does your TV support HDMI component cables? Does it support DivX, WMV, XviD, and other file formats? Does it support video/audio streaming? Each of these questions matters most based on your preferences and available technologies. If your TV only 720p, that doesn't matter. If you don't download from the internet, neither does the other format question. However, the support for video/audio streaming could be useful if you ever decide to stream video from the internet.
• Does it have 5.1 audio? Do you have a receiver or do you need one built-in to the DVD player? This one either saves you money by not doubling up on something you already have or nets you one box for two uses.
• Would you be better off with a Home Theater PC? Cost is the biggest issue between these two options, but perhaps you really need something that can cover all of this and DVRing, internet access and gaming all in one?
