DVD ripper is a computer program that facilitates copying the content of a DVD to a hard disk drive.

DVD Ripper can rip DVD to AVI MPEG WMV DivX H.264/MPEG-4 AVC MP4 MP3 WMA excellently.

pavtube is one of the best dvd rippers, It is versatile application and users can use it either to backup DVD to hard disk or to convert DVD movies to AVI, WMV, MPG, MP4, MOV, and 3GP, AAC, MP3, W4A, WMA, WAV and AC3 etc.

there are many places to download games for free here are some that you need to use torrents on, a good way to make these torrents work is by going to utorrent.com , you must have a homebrew psp to make these work

Having a smaller screen would not worsen the graphics, with a smaller screen come less pixels, thus the graphics would be better. unless Sony used the same amount then it would be exactly the same. This however would be unlikely. And no new hardware would be needed. The old PSP would not become "obsolete" because only the pixels would better the graphics nothing else.
just goto the browser and delete your cache,input history, and cookies. it will restart the portal completly. have fun :)
