I wanted to follow up on the helpful post above. For Mac users, updating the TinyTV2 is likely to be a confusing process, even if you're technically adept. If you open the update site in Mac's inbuilt browser, Safari, it will describe a process for downloading files and copying them to the TinyTV. But the folders described bear no relationship to the ones you will see when browsing the TinyTV files (with hidden files and folders revealed). Web instructions also refer to pressing the TV's reset button, but no reset button is documented. There are two holes underneath the TV, but I can't tell if either is a reset button, and I didn't want to poke too hard at them in case they weren't.

Updating the TinyTV2 is best done through a browser, not by copying files. The option to update by browser won't work in Safari, and Mac Safari users will not be aware this option even exists, because this is not documented.

The best way to update: plug in the TinyTV2 to the computer, open Google Chrome, then connecting ot the TinyTV.us site using that browser. Selecting update on the top of the web menu will start an update process that is carried out within the browser. This is a fairly straightforward process.
