[daip] TVMOV fails for 1024x512x4 cube

[Laura Spitler]

Dear DAIP,

  when running TVMOV to display a 1024x512x4 cube, the TV seems to load
correctly (although the images appear in the bottom of the screen, which is
a little unusual), but TVMOV then has some odd bugs.

31DEC03 dies before executing the actual movie.
The messages are as follows:
  >tvmov
  AIPS 1: Hit button D to terminate load prematurely
  AIPS 1: Cursor X position controls frame rate or selection
  AIPS 1: Press button A to start or stop the movie
  AIPS 1: Press button B to switch the direction of the movie
  AIPS 1: Press button C to enhance the image (color or B&W)
  AIPS 1: Press button D to exit
  AIPS 1: TVMOVI: ROUTINE YCRCTL RETURNS ERROR CODE    2
  AIPS 1: TV PROBLEM

Version 'NEW' and 'OLD' don't die, but seem to think the individual planes
  are 1024 in the Y direction rather than the X -- i.e. the movie chops
  off half of each plane.

The inputs are given below.  The setting of docenter doesn't seem to matter.
Setting TXINC 2 works fine, but then (1) all the images are loaded into one
TV channel, and (2) the image is of course stretched.  Anyhow it seems
unfortunate that TVMOV does so messily rather than gracefully bitching
at the user for doing something stupid.

  Cheers,

             Michael & Laura

p.s. This was run on spitler, a Gateway linux box.
