Hi Signals, thanks for your quick reply but...

In order to create an output *.xvid (.avi ) file with a fixed video bit rate of 175 kbps (when you look at the properties tab for the finished file). I have use the "video bitrate box" and fixed it to about 1300 (1298 ish), but this does not always create a 175 kbps file (+/- 2kbps) and both of my players have trouble playing the output file.

In addition the frame resolution doesn't seam to be as source as black bars seam to be added to generate 16:9 & 4:3 res. if I could keep original this may help eg. 720x384 etc.

All the above could be wrong but any help would be greatly received,

Thanks again for all your help,
Bye for now,
