I have seen this issue.
It was related to openGL as I recall.
try using the arrow keys to move around a bit that will probably get the 
intro menu back.
go into the setup menu and turn all the openGL stuff off.
there *might* be something in mythtv-setup to do the same as well but i 
forget now.

The default resolution was very low with what came with the installation.  I spent quite a bit of time finding the right drivers and now I am getting 1680x1050.  I think those were restricted drivers that I downloaded and installed.

I don't think that first screen doesn't present any challenging graphics.  The screen is totally blank with that swirl of a blue pattern.  Randomly clicking somewhere will bring up various screens that are completely readable. I was hoping to randomly click on something that represents "View Live TV".
