[MPlayer-users] A/V sync off on x86-64

Hi all. I have built MPlayer from the CVS on Fedora Core 5 for x86-64 and have 
a problem. There are some .mpeg files I have pulled off DVB-T which when I 
play them the A/V sync is all over the place. The problem appears to be that 
the frame count values have become so large that the floating-point 
representation is no longer accurate enough to work out the difference 
between them. I suspect this is to do with the 64-bitness as the same file 
plays OK on a 32-bit build. Here's the terminal output for illustration:

A:204963825319936.0 V:204963825319936.0 A-V:  0.000 ct:  0.000 931/931  7%  0%  
0.7% 0 0

If any developers need more info to fix this, please ask!
