Preview video refresh

[jhobbs]

Preview of most .MP4 files is perfect.
But there are three categories of .MP4 files:
- "Good" files (most of them)- no issues
- "Iffy" files- Usually preview fine, but sometimes fail to display properly after previewing several .MP4 files. "Refresh (Alt-Shft-R) does not help, but Closing and re-opening xyplorer always displays "Iffy" files correctly.
- "Bad" files don't display at all, or display as a thin band of video.
Note: VLC always displays the files correctly.

Windows 10 64-bit, Intel I7 Ivy bridge, 16GB.

Could you please resolve the issue entirely, or fix Refresh to "restart" the display mechanisms?

Do you have a link to download an iffy one?
