Since The 2 Gig memory sticks are coming out and a slew of memorystick products are coming down the pipe, 256 mb- 1 gig ones prices are droping fast. I reccomend a 1 gig one for all your movie and music needs. If you need to convert your movies to psp mpeg4 format(the only movie format psp plays), search google for 3GP_Converter. if you have any questions about this converter(its all in japanese) contact me at davis15945@bellsouth.net. (please dont send trash to this adress) Glad i could help Happy
