I may have found my answer in this thread: http://team-xecuter.com/forums/showthread.php?t=97109is i said in my previous post, start your own thread.
the oscillator (what you call crystal) is fine (green led is flashing) and the video does not prove anything since you arent measuring the signal on its output!
im sure it should measure 48.000000hz +- 5 or 10 ppm.
I did not know I could not flash the DGX, and I just tried to program it with the Nand-X in one of my attempts at using the jed 4-3 JRunner
