Video overlay scaling and MPEG playback scaling are different.  For
video scaling the gfx driver has to export the scaling interface for
other X-Server modules, so v4l can use it to setup the hw overlay for
video.  Not all drivers do this...

xawtv uses that in grabdisplay mode, i.e. if the hardware doesn't support
overlay (usb webcams, whatever).  Try "xawtv -noxv", then turn on
grabdisplay manually, then fullscreen.

Hmm, no vidmode extention available?

Works fine here.  A few older versions take numbers only, not "on/off"...

... but this one should work fine.
