MPC and XVID aspect ratios

[J_Freak]

I encode DVDs to XVID (Ver 1.1) using Avisynth to crop just the top and bottom (black patches) without touching the active video area.
So I end up with the same number of horizontal pixels (720 usually) but less vertical pixels than the original video. While encoding to XVID (with VDub) I select the pixel aspect ratio and select whatever aspect ratio the original vid had.
Now Media Player Classic (Ver 6.4.9.0) displays the encoded video stretched vertically and I have to manually lower the height of the video everytime I play. The aspect ratio is set to default in the player and the "Keep aspect ratio" is not selected.
Nero Showtime plays the videos fine without and fiddling. Can anyone shed some light on how MPC handles aspect ratios?

Resizing works fine here in MPC.

Not so much upto MPC though. What decoder are you using?

I use the XVID decoder and ffdshow. U think using display aspect ratio instead of pixel aspect ratio would help?
Like i mentioned, Nero Showtime plays it fine. I'll have to check what decoder Showtime uses.

select par in xvid: i.e. for 16:9 pal 16:11

try different video renderers (VMR9 renderless works well) in mpc with ffdshow (overlay mixer enabled + allow output format changes during playback). then there shouldn't be eggheads anymore...

Guess what? I enabled Video Frame>Keep Aspect Ratio and set Overide Aspect Ratio to Default and it's just fine.
I thought Keep aspect ratio meant remember the last a/r used and apply it to the video that is being played. Duh!
