aspect ratio (solved) and AVI open problem (SOLVED!)

[Digiface]

that file used to open fine with older BSPlayer,but now with 2.10 it won't open. when i try to open it ,BSPlayer hangs and even makes explorer.exe to restart and after that video starts to play. but if i right click tray window (before explorer.exe restart) and choose "close",then window pop up and says that file cannot be found.

so i think that it might be somekind of bug in BS.player 2.10 with certain files,while MPC opens it fine. i have tried with random files and so far only had problem with this one file.

EDIT: MPC ja VLC plays that file fine,but example BSPlayer and WMP won't. what's is happened to that file? it used to open fine. can defragment damage files?

EDIT: i check file with AVImedic and it says there was 0.1Mb (49Kb) of fake data. and files that work have none fake data.
