Video Playback - Helped by faster SD card?

[Guest symbiotix]

Hey all,

I'm running the trial version of Rock Player and I've noticed that higher rez divx files occasionally come up choppy, and 'seeking' is very delayed (ie. you slide the progress slider and about 10 sec later it responds). Has anyone tried a faster SD card than the one that comes with the unit? The stock card is merely a 2x so I was thinking that a 6x would solve the problem. Any advice is appreciated!
