I recently bought a LCD picture frame for my wife and it supports DivX. I was wondering if we could play full movies on it. If that is the case, how big and how fast does the SD card need to be.
Size will matter on the size of the movie, and for some reason I'm thinking that the speed of SD cards is pretty much standard. FYI: I picked up a 1GB PNY SD card @ BestBuy for $20 this weekend if you're looking around.
SD Card transfer rates are measured on the same scale as CDROMs (150kb/s intervals).
Basic SD cards transfer at 6x (900kb/s), 66x cards are about 10Mb/s, and faster yet are 133x, at about 20Mb/s.
I'm not sure what the sustained bitrate is for DivX exactly, but you're probably good if you go for a 66x 1GB card for a 1.5 or 2 hour movie, if it will play them at all. This is also dependant on the version of SD protocol the frame uses, which should be 1.01 (supporting 66x) or 1.1 (up to 133x) if the frame was made in 2006 or later.
