Cannot specify Bit Rate in Gknot

[benafk]

I have been using Gknot for a couple of months now and am fairly familiar with the program. I have it installed on 3 different computers, but am having a very strange problem with one machine:

I usually go for 2 X 700 Mb CD's for size and try to achieve a bit rate around 1300.

After the bitrate and resolution settings are complete I go to the preview window and choose my final options, which are very basic.

On both the audio 1 tab and the DivX 4 tab, I have unchecked "re-calculate bit rate"

My problem is that when the encoding job is done by Virtualdub, the bit rate is always set to something around half of what I set in GKnot. The file size is also roughly half of what I set in Gknot.

I cannot seem to get the bit rate I want and its driving me CRAZY

Gknot performs fine on my other 2 installations.

Has anyone seen this problem before?
:confused:

Something like that happened to me once when I opened the .avs file with the "Frame Server Credits" button instead of the "Frame Server" button above. Then, of course, the whole movie was encoded at the end-credits setting which was also about half of the desired size in my case, as far as I can remember.
