error in virualdub

[katio]

When I use divx 5 with virtualdub there is an error:

Video coach warning:
Virtual dub has detected a potential problem
Fast repack mode is selected.this can significantly speed up recompression times,but may cause error with codecs that do not properly support YUV formats.Check your output file to make sure the input and output code are compatible.

What can I do?

thanks

DivX fully supports YUV so it is not a problem. This is just a warning message. Press ok and enjoy DivX 5.0.1

...and if it doesn't work (but it usually should work), you can always use normal recompress
