This application is a video player from our PSP’s browser. Simple, but very useful. It has several advantages over other similar programs like PSPTube because it uses the RAM of the PSP as a cache, which makes impossible rewind the video. It also has a nice graphical interface and more.

There are problems with viewing videos in 4:3. The cache management is still not optimal. Homebrew tested [on] 5.00M33-6/5.50GEN/6.20 PRO CF-B5.


Improvements:
•Improved graphical interface.
•Compatible with custom firmware 6.XX
•Still fails with JavaScript and videos in 4:3.
