Openbox S9 HD PVR - firmaware good for recording and playing on openbox

Hello everybody from Mongolia.

It's my first post and I wish you all the best , my friend sat.

I have a OPENBOX S9 HD PVR, i verified it , it is a genuine openbox , not a clone.

I would like to install a good firmaware that permit me to record channels in avi or mpeg to be more useful on PC and also that permit me to use my OPENBOX for playing this video, use it like a video play and record.

any suggestions ?

thanks all, have a good day
