Are you sure, this will work ? As far as i know some frames between the i
frames contain difference information. And if we add something to the i
frame it will "fade" away in the next frames until the next i-frame !?
It will only work properly for stream with very less movement/changes.
Anything else will lead to hard readable OSD !?

But what if we show complete menues (on black), without the live picture in
the background ? This could be easy done by just displaying i frames !!
And for the short epg info the 4-color-overlay is enough ?!

Yeahm, you're right, i forgot about these things :-)
ac3 out via spdif would be extremely useful ...
