Loading Videos Crashes XnView

[Jdev]

When loading a page of several videos, often times some one or more video(s) won't load and will crash the program.
The "problematic" video(s) prove to play just fine in other programs.
If I isolate the video(s) in a separate folder sometimes they will play without crashing the program.
XnView is the only program that I've used that is hyper sensitive to this loading process.
ANY help!?
Thanks!

I have no problems but most of my videos are MKV or MP4's re encoded with DVDFab Converter

Don't use old stuff like FFDShow it's unsupported, DivX or Xvid.
I have LAV Filters and madVR installed for MPC BE 1.5.0 but XnView won't use them
