So I got a Sandisk 8GB Class 4 MicroSDHC from DealExtreme when I got my SuperCard like last April and for some reason, SuperCard auto detects the read speed as a speed of 5. My friend's Kingston 8Gb Class 4 MicroSDHC on the other hand gets detected with a read speed of 25! Does this seem right? I've formatted the card numerous times, and I can't even get past the full format when using the Panasonic formatter. The card works, but I'm beginning to think that I got a fake. If I do have a slow card and it's the reason behind why my DS videos are out of sync, then I may purchase a new one. Can you guys recommend me a good, fast MicroSDHC card just in case I need a new one? Thanks! Can a slow SD card cause problems when playing DPG4 videos on Moonshell? DPG videos that were originally converted from AVI works fine, but if they're converted from RMVB format, the sound gradually gets faster than the video.
