I'm having some trouble with mplayer with the tvout on my pvr-350

I've tweeked the settings for mplayer to be:

mplayer -fs -zoom -quiet -vo fbdev -fb /dev/fb1 %s

So now my files (ie. the avi I tested with) plays on the screen. However, two problems. I don't seem to have any keyboard control. I actually have to switch to a terminal window on the monitor I still have hooked to the machine and do a kill on the mplayer process.

The other problem is it's not really zooming. It's only taking up about 1/4 of the screen right in the centre.

After looking around here and on google I can't find any references to this. Anyone know how to both get it to zoom and why I have no keyboard control?

Thanks.
