I think I have to test this with tv-out too as I didn't get the effects
you described with vga out.
You can however do the following (if you like):
- If you've still enabled youre usleeps, disable them.
- dirtyLines in GetLockOsdSurface() should be cleared by:
as sizeof(dirtyLines) is 4 :-) .
- I guess method ShowOSD() can be dropped. Dropping should be ok now
for live-tv, but needs some extra handling when paused. In that case
handling from video:Action() should be like
current_osdMode == OSDMODE_SOFTWARE.
