     I think that's the TLA for the ULowell board:  Professional Video

     Though they won't admit it, there was a bug in NewTek's Dynamic
Hires viewer program.  *Any* speed-up of the Amiga, from an A2630 to a
CMI Processor Accellerator, will cause this obnoxious distortion. 
Booting with an '030 or '020 card in 68000 mode, or the PA at 7MHz,
will let the program work fine.  Evidently there is some sort of
software timing loop.  I think that there was a fixed version of the
viewer posted to CompuServe not too long ago.  (I don't have it.)

TLA?  Oh, that stands for Three Letter Acronym, of course.
