Virtual dub- MMX left on

[MrPhelps]

Hi, I am trying to take a avi and convert it to a mpg. When I scan the avi for errors in virtual dub after 1-2 minutes it says "Internal error: MMX state left on"

How do I turn it off????

MMXisn't the problem:

Visiting the software's support pages is always a good first step.

Thanks I should have known better than not going to the site.

I do read a lot of posts and the group here is first class.

From the VirtualDub knowledge base:
PRB: Internal error: MMX state left on during video scan 1.4.10 (13870)
symptoms You receive this error during a "scan for errors" command:
Internal Error MMX state left on: T:\projects\VirtualDub_old\main\VideoSource.cpp:11 01
cause 1.4.10 performs MMX state checks before and after certain calls to third-party codec drivers. Leaving MMX on results in floating-point computation failing; the check going in is designed to protect codecs against crashes that would be caused by VirtualDub, and the check going out traps potential crashes in VirtualDub caused by codecs. There is a bug in the video decompression code that causes the going-out check to be bypassed if a decompression error occurs. It appears that the Microsoft MPEG-4 V3 (a.k.a. DivX 3.11a) codec improperly leaves the MMX state on if it detects and reports a decompression error back to the client application. This error is then misreported by VirtualDub as an internal error instead of a codec failure.
workaround None. The misleading error message will be fixed in the next release; a code workaround for the codec problem will be necessary since that codec is no longer being updated.
