PS3, DVD, and video files

OK, so I can transfer videos from my computer to my PS3… It supports the following formats.
MPEG-1 , MPEG-2 (PS,TS) , H.264/MEPG-4 AVC, MPEG-4 SP MUSIC, ATRAC (.oma .msa .aa3) , AAC (.3gp .mp4) , MP3 (.mp3), WAV (.wav) IMAGES

I dont know what half of these are besides MPEG, so all im really looking for is MPEG formats on Limewire, finding alot of AVI files just not MPEG…
and just now i found software called “PS3 Video 9” a video format converter, im going to try this and see if it works… If it doesnt work does anyone have a converter i can use to convert some of these video files without a watermark and is easy to use?

also where does everyone get DVD movie or TV show rips or copies from?

UPDATE:
the ps3 video 9 converter works! woot woot
just tested it with an episode of the real ghostbusters cartoon.(lol i feel like im 9 years old again) copied it onto my ps3 and it works in great quality, now im in the process of downloading some DVD’s. ( Wish i had fios… :frowning: )
