I would like to put the video from my Sanyo hd1 video camera, which uses SD cards, onto the av500 for temporary storage and possibly viewing. Does it have a SD card reader slot? If not could I plug in a Sd card reader into av500 and drag and drop data so I can continue to use my video camera w/ second card as 1st card is being copied? Is it possible to view the unedited mpeg 4 files on the av500 or do I have to convert 1st? If this is not best option for what I want to do, do you know better options? I would perfer not to lug laptop around and I need more storage space.
