Re: Whats the best screen locker app?
 

Its not free, but if you're looking for video you could try yxflash.

Slingplayer is working on a private beta right now I think, with an expected release this summer.

If you're looking for Total Commander, as in the file explorer version, you can try Astro from the Market, its free, or EStrongs File Explorer.

try astro player. I used coreplayer on my tp2 and it is the closest I have found.
