deinterlacing problem with Bob and Yadif(2x) mode

[mstale]

Hello!
I tray to deinterlace video before encoding (actually I want to transcode and streaming MPEG2 video) using “Bob” or “Yadif(2x)” mode, but VLC is crashing.
It works only with “blend” and “X” deinterlace mode.
I’m tried with 1.12 and 1.05 version and result is same, and with Vista and windows 7.
Is this some kind of bug or something else???
