[XviD-devel] xvid_bench from HEAD cvs gave me 2 quantizer CRC errors...is this expected?

I'm using .NET Studio and want to make sure it's not my config...

Also the time calculation seems to be wrong for win32.  On mine it causes 
some negative times to be displayed.  Not sure if it's different on other 
versions of Visual Studio, but in .NET "CLOCKS_PER_SEC" = 1000.  And if I 
change the following line in xvid_bench.c from...

return clk * 1000000 / CLOCKS_PER_SEC;

to...

return clk * 1000;

It fixes the negative times.  I'm guessing it multiplies first then 
overflows the int.  Parenthesis would probably fix it too ("return clk * 
(1000000.0 / CLOCKS_PER_SEC);"...added the decimal to make the result a 
double just in case).

Thanks,
Joe
