I agree, the new box is slower and the smaller on screen text is another problem.

I also observed random channel changes, not sure what is triggering channel change when none of remotes were operated.
USB port could be for future feature supports like using external USB HDD or pen-drive to record.
I am using USB pen-drive for recording on Airtel STB.
