screenshot of preview window with some minor UI glitches

While attempting to encode a video using the program MeGUI, a preview window
appears which shows filters and effects applied to the video before it is sent
to the encoder.

In many cases, this window does not appear, and a “Fatal error” message appears
with the text “MeGUI encountered a fatal error and may not be able to proceed.
Reason: Value was either too large or too small for a Decimal.”

Wine also prints the following line:
"fixme:variant:VarDecRound semi-stub!"

I noticed this only happens when attempting to preview videos with certain
aspect ratios. Videos of specific sizes, such as 720x480, can be previewed as
they have aspect ratios of 1.5. Other videos, such as widescreen 1280x720
(aspect ratio of 1.7777… repeating) cannot be previewed and display the error.

Interestingly, although you can’t preview the video, you can ignore the error,
continue to encode, and the output file will be the proper size.

If you try previewing a 720x480 video, and then set the aspect ratio to some
never-ending decimal from the dropdown menu, and try to preview that by
clicking the “Preview DAR” box, the error also appears.

I’m guessing there’s something wonky going on with how Wine is handling
numbers?

FYI, the MeGUI requires .NET 3.0, which I installed using "winetricks dotnet30”

I installed Wine via MacPorts repository, using “port install wine”

And somewhat related, while encoding, the progress window that shows % complete
and frame encoded per second doesn’t properly update and returns the same
“fixme” message. Not sure if I should make another report on that, as it’s
closely related.
