S60 (Symbian)

Hi, I've bought a 6600, and can honestly say it's the best phone I've EVER owned, I use it more than my PDA...I'd really like to put videos on, and am currently using a 128MB MMC card (also did you know, even though they are fundamentally the same, the 6600 won't accept the SDcard as a sub for the MMC) so CAN fit videos on...I've also scoured the net for converter proggies to convert AVI/MPG to 3GP and RM files, I have the latest version of Real Media player (for this phone) BUT, the player doesn't seem to want to buffer larger files, and makes a clicky noise through the speaker, is there anyway I can watch my Family guy, Scrubs or Red Dwarf videos on the bus/out and about, without this problem? Many, many thanks in advance.
