Yes, but it doesn't make any difference (x11 behaves the same as xv).

Hmmm. I'm runing 1280x1024 (highest I can). I tried scaling, with
"-xy 0.5" for example and got a nice window in the middle of the screen,
but the size restriction messages continued and the problem still
occurred.

Using larger -cache values delays the problem (usually it will exit with
"End of file" messages) but nothing works completely.

Even the video that is played seems wrong; it appears to be running at
less than real-time. That happens with captured data too.

What size restriction does it mean? Is it saying that it's too big for
some internal structure, too big for the display, or out of spec? The
message is not at all helpful.

That didn't help. I'm not getting the message that often (once a second
or so).


Thanks,
