it sounds like an offset problem, or maybe a LCD scaler issue.  As I
recall I had Xv working pretty well at all resolutions on my savage
IX, but it's been a while since I tested.  I don't have a supersavage,
so it may be supersavage related (although I think the overlays are
pretty similar if not identical).  Do you have problems with all YUV
formats or just some?
I must re-iterate that the savage streams engine is a work of pure
evil.  I REALLY dislike working on it.  If anyone else wants to try
their hand at this, let me know and I can answer any questions you may
have.

I upgraded the t23 to a 1400x1050 LCD display and now again only in
the highest mode (1400x1050) I can
use xv. Sounds for me like a simple LCD scaling issue. How can I fix this?
