OK here are just a few good movie sites for iPod/iPhone also can get these to work with other devices and play on PC as well !
http://ipodmovie.info <--- NEED TO CREATE AN ACCOUNT TO USE
on the iphone you should download the app !!!
I also want to tell of some good APPS to use with it on iPhone or iPod Touch:
iFile -- you have complete acess to your file system and can move and store movies on iphone
dTunes -- also download movies and MP3's to your iPhone also has other great features
MxTube -- Downloads and plays youtube videos -- NO ACCOUNT REQUIRED
Unlim Videos -- Downloads and streams movies -- NO ACCOUNT REQUIRED
PhoneFlicks -- is bacally Netflix on your iphone $9.99 subcrition required
Dont use
Free Flix --- Waste of TIME and crashes
Remember you can use a cable like this to play your ipod/iphone on a big tv
But also note the lower quality videos wont look good on a 60" TV Some of the movies I downloaded on my IPHONE still look great on the TV
