I still use the media server. It works very well. 1080's will kak off when loading, and if you ffwd or rwd it will crash the player. But the spec of the Server itself is slightly better than a ZX spectrum.
Personal opinion on "jailbreaking" the ps3.. not worth it. You lose all online game functionality eg No patches, no updates for the firmware of the system itself, no no no! AND you will ALWAYS have issues with newly released games.
Think about this:
Brand new game +-R650 on release day.
1 week later - Same game 2nd hand = R300
3 weeks later R200 or less.
Or take your old games that you dont play anymore and trade them in towards a new game.
Eg: SBK-X = R600 brand new
Im trading in:
Star Wars Force Unleashed 1
Heavenly Sword (Platinum)
Ratchet and Clank (Platinum)
Fifa 11
Thus equating to me having to only pay R100 for SBK-X
