Quite simply,  I want to test raising the file limit from 100, to a higher number on the TinyTV2.    I've been trying to figure out how to use Arduino IDE,  but i just keep getting errors.  I figured out how to batch convert my own mp4's to .avi at a lower bitrate to save on file space.  But more than that, and i'm out of my league.

Anyone know of any video's that gives a good tutorial on how to use Arduino IDE, or more detailed instructions on how to edit the firmware myself, and then upload it to the TinyTV2? 

I have already opened my TinyTV2, replaced the micro-SD card.  Have have zero fear of messing something up, or bricking my TV.  I just want test higher file limits, so I don't have to turn entire seasons of shows into single files. 

The good news is, I can confirm that you can raise the limit, at least somewhat -- I've turned it up to 200 and haven't had any problems yet.   (I never added that change as a pull request on the official firmware though, because no-one ever answered me about if there was some downside I'm not aware of -- although they seem to have stopped merging pull requests anyway...)

Can you be more specific about the errors you're getting?  Arduino IDE is working for me, although I don't remember what steps it took to reach this point any more...

quite simply...........I have no idea where to put all the fimware files.   The instructions on the site just says unzip the libraries, and put the folders inside the src, into the libraries folder of arduino.   But what about the 3 zip files?  And what about all the files NOT in src folder?    I keep getting "file does not exist" type of errors, for things like TinyIRReceiver.h or .hpp, or a JPEGDEC.h or .cpp does not exist.  etc. 

That's the part that I'm basically stuck on.   I want to simply test if I can go to 999.  Since it can do 100 files, and that's 3 digits, I want to see if it can do 999.   If not, I can just combine my video files, and make entire channels for individual shows.  But if I can raise the limit, then I can have each channel be an episode. 

I'm not sure what you mean by "unzip the libraries [...] but what about the 3 zip files?".   The 3 zip files *are* the libraries that you're unzipping.
