I am not sure if I will be able to help you much but I am going to try my best and will ask Gilles to have a look at this post as well..
DisplayAspectRatio/String : 5:4
FrameRate/String : 29.970 fps3
Standard : PAL
Seems to me that usually Pal is 25 FPS and Ntsc is 29.970 FPS so already here we have something out of the usual ..
Also the apsect ratio and video sizes in the second options are also uncommon .
You may try to begin to place your video in the active worksheet ( take the smallest one for tests) click on the xvid icon choose in the summary choose xvid avi custom resize.
If you are not sure for the proper dimensions click and select the video submenu from there you can choose standard video sizes and aspects you can also change manually the W and H if you wish
If you are in the states the system is NTSC in Europe PAL or Secam usually
An alternative solution would be to go in expert mode and crop de black bands
Thanks for letting us know the outcome
Have a nice day
