The "grey and blocky" screen is somehow corrected in on of the current XBMC or firmware versions. So I think it will be gone with one of the next released versions.

The other fact is that ffwd and rwd didn't really worked well in XBMC as far as I read it. In all posts I've read about this topic the last weeks all members suggested to use the seek function to jump in steps of 30 seconds and/or 10 minutes.
You can adjust these steps in the advacedsettings.xml to custom values:

sorry to sound a bit thick, how do you go about doing this?
thanks.
