yeah, dvd's definitely look better on the ps3 w/ the up scaling. it really does improve the picture quality.
and joker, check out
www.newegg.com for those cables. i got three 6ft hdmi cables on there for $10 when i got my ps3. they have really good deals on electronics on that site. i also got a 4gb miniSD card for my phone for $3.45 w/ no shipping costs.

i would suggest to both of you that you look into media server programs and start using them. i use PlayOn media server and windows media player media server. you can stream tons of content from the web onto your tv for free. movies, tv shows, music videos and pics from your hard drive... etc.... and a lot of it is in HD

also, if you have netflix, get the disc sent to you. it's only like $9.50 a month for unlimited streaming and one dvd by mail at a time. like i told other people, i don't even have cable any more cuz i get all my dookie off the web on the ps3
