-You must use <option>-vo vesa</option>. The tested chip was capable of 1.333333

-Known issues: VESA-only, 1.33333 limitation, image isn't always centered,
-movie becomes 4bpp in every 10 minutes, and stays that way. Frequent hard
-freezes, LCD display problems.
+The Neomagic chip is found in a variety of laptops, some of them are equipped
+with a simple analog TV encoder, some have a more advanced one.

+  <simpara>Mode 512x384 is not supported in BIOS. You must scale the image

+  resolution you need to replace two tables in <filename>vbelib.c</filename>.
+  See the vbeSetTV function for details. Please contact the author in this case.
