I have a problem in finding out what size USB drive I can use. I have tried 2 different 16Gig USB thumb drives and both did not work. I formated them to fat32 and still not seen. I have a 4 gig that woks fine. What size's should work and whats the deal on brand?

 

Is there a size and type of SD card I need. Will an HC card work? can I use a 16 gig card?
