Along with many others I got my tinytv for christmas and I'm loving it. What I have learned from searching the forums and playing with it myself is that AVI files get HUGE. Especially when I try to convert an 8 hour+ long video to mimic a real tv channel. I already know I'm going to have to upgrade the microsd card. I'm almost there though, and my final hurdle has finally revealed itself. It seems that the card being FAT32 is a hard rule, does that also mean I am absolutely limited to 4gb files? If that's the case, is it possible to program the tv to create channels from folders full of smaller files? Thanks all and happy holidays!
