I believe this was discussed by > the Stella at 20 guys a while back -- check the archives. Also, 3 scanlines of VSYNC is *not* enough. To be standard, at any rate. :P If you add a few more sync pulses, it's better. I forget what the "official" correct number is, (Glenn?) but it's higher. 3 is about the absolute minimum that most TVs will sync to. Newer, fancier equipment does expect to get a correct signal. Not an unreasonable expectation, but sometimes not good. Anyone remember why can't you do calculations during VSYNC? I remember the discussion (a couple years back), but I don't remember the details. -Chris -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
