After install video output is set to pal output like it should be.
Regarding video wall search

. .. Is based by jumping to the first movie which name start with letter input by user. I find more easy to navigate trough pages by pressing button numbers. I got 3 moviewall shortcut to movie folders and 2 of them have more then 25 pages and always have a idea about any movie location.
I remark the Samba improvment, it is not much but is there.
I find that moviewall eat to much resources when navigate trough movies by pressing or keeping pressed the left / hi button. Sometimes you fine out that from page 2 jump to page 8 or 12.
Thinking at GUI 2.0 i like features like input history, don.t know about prefilled text or other etc, but is to chinesse. It look like old sigma gui and his concurents. I hope that Sanji will add his custom view and work to this.
This SDK have same root but it has optimized code. So for so good. Still need + ++
