Romik,
This is fairly common, as ver. 4.00 is still a bit unstable.
Simply uninstall 4.00.

Download and install 3.68.
Once installed, in order to obtain 160x128 resolution, you must edit the AmvTransform.ini file. Open it in notepad, and in this string:

VIDEOSIZE=96X64(8;10;12),128X96(8;10;12),128X128(8 ;10;12)

insert 160x128(8;10;12)

reboot, and test. Post back results.
Good luck,
I
