Howdy
. I love how the 1.6.1 went back to the 1.3a&b designs - its sooo retro ^__^

To discribe what is happening can best be understood as - the Wrong Codec.
( but `just barely wrong! ) 16 X 16 squares of "Ą" with green background ....

I can either link the Video section -or- a stand-alone picture of the bleep's for you.
? what are your Rules for Picture Sizes, I might be able to link the Picture directly.

. why I call this an Error is because 1.3c & 1.4.10 & 1.5.4 do not produce these squares.
I'll await a MOD's reply on how to proceed from here

There's no limit on picture size AFAIK, but I don't know how useful pictures would be. A link to the actual MPEG (or a small portion which exhibits the error) would be the best thing.

hmmm . . it just dawned on me; how do you cut a Mpg file?

The most compatible way would be to use something like TMPGEnc's "Merge & Cut" function (in its "File / MPEG Tools" menu).

But MPEGs are kind of like endless streams, so alternatively you could use VirtualDub's hex editor (in the "Tools" menu) to extract a segment of the MPEG. If you extract from Address = 0, the result should still be playable. You have to type the length you want in hexadecimal, for example: 1000 hex is 4 KB, 2000 = 8 KB, and so on.
