..snip...excellent information

Thank you for this wealth of information!

I checked and found an older copy of AnyVideoConverter, [16MB] circa July 2010 installed back when I was trying to view other videos. I had tried that version of AnyVideoConvert at the time and it failed miserably on this machine.

My machine has not changed since then [I think, perhaps kernel got installed]

Are you certain that later versions of AnyVideoConverter would work better? Seems to me the bloated code, going from 16MB to 31+Mb, would be more to address WinXP, etc.
