The source code to TinyTV2.h says that the maximum number of video files is defined as 100...  Would it be as simple as increasing that number if I wanted to raise the limit, or is there a technical reason that it can't go any higher?   (If it's about the number displayed in the corner when you change channels, I could fix that to match...)

well, fwiw, I just bumped it to 200 and everything still runs, and I was able to view 101 files just fine; I didn't even have to change the channel-number-drawing routine?
