A lot of DSL modems actually have routing functionality that interferes with your actual router. They tend to use a PPOE setup, which means you have to tell your modem to not do PPOE and use the settings that it had to tell your router it's a PPOE connection, complete with the login user/pass and external IP address the modem was getting. I know that sounds complex, so maybe just google on that subject with some keywords and you'll likely find the steps for it.
I'm deciding between Netflix and Blockbuster's online rentals. Has anybody used the online streaming service with Netflix? If so, here's a few questions:
What is the selection like?
How is the image/audio quality?
How smooth is the playback?
