You have to convert videos for PSP format which is a pain although yeah its fun to watch movies and stuff on PSP and its really good for spending time while traveling and stuff like that. You can listen to music but thats not something special, you can listen to music in all mobile phones the sound quality of PSP is fine not that good not that bad.
1. Im not sure about that because i bought my PSP when it was released so then i did the downgrading and installing custom firmware and everything myself with the help of pspiso.com
2. No there arent any Psp Dvd's availible. The PSP game's come on a UMD which is a small disk which is fitted inside a case. UMD reader is not availible to anyone but sony (as far as i know) so you cannot buy a empty UMD and save on a UMD so hence you cant play games that way. The only option is to copy games to the Memory Stick and load them from there. These umd's arent the same as small dvds which are available in the market.
3. here are some differences i found between the Fat and the Slim PS2 to help you make the decision:
1. The original (fat) PS2 uses a simple AC power cord, whereas a slim PS2 requires an AC to DC adaptor.
2. The original can support an optional HDD (hard drive). (Note: I'm not sure if all games will support it). The slim does not support any kind of hard drive.
3. To play games online with the original PS2, you have to buy a network adaptor to attach to the expansion bay. The network adaptor is built-in on the slim PS2.
4. Disks are placed in a disk tray on the original model. However, disks are top-loaded and clicked-in on a slim PS2. (Note: It is easier scratch disks when you place them in the slim model than it is on the original PS2. When placing disks in a slim model, you must be more careful and watch what you are doing. You can't just haphazardly toss them in:smileyvery-happy:!)
5. The multitaps made specifically for each model are incompatible with each other. Even the third-party ones that are supposedly built for both will often not work on the slim model. (This happened to me. I have the original model, and I bought a multitap that would work on both models. Since my cousins have a slim PS2, I though I would try it on theirs. However, their console wouldn't even turn on. I later found out that slim models might not have enough power to run a multitap made for both.) Regardless of which model PS2 you get, get the official Sony-manufactured multitap that is specifically made for that model (original or slim).
6. The original models have had more overheating problems and disk-reading problems than the slim model. Also, in many of the original models, the disk-reading laser has burn out overtime (mainly because it has been around longer and has therefore been used more). Most of these problems are either isolated or unheard of with the slim model.
7. The original model has been canceled in the US. The only place you can get one in the US is at a used game store (like EB Games or GameStop) or online (Ebay, to name one). However, they still make the slim model in large numbers.
Anyway what i think is that, PS2 is more good for gaming and gaming only. PSP is a bit more flexible, The gaming isnt as good as on the PS2 but there are alot more features in the PSP then that on the PS2 plus you can even install custom applications on your PSP. I installed one software through which i made my PSP into a remote control for my Sony TV.. PSP has an infra red too so through that it became a remote for my TV.. Lol. So there's alot more you can do with the PSP, although yeah i got tired of the games on PSP pretty quickly.
