Seriously?  MPEG-2 at 35 Mb/s ???   

Seems a bit iffy.   I think you should consider re-encoding at MP4 or H.264 for this type of material.

I think the root of your problem is the super-high bit rate.

It’s run fine on the computer because you have higher I/O path between an HD and the PC…  

Are you trying to serve this over wireless?  Wired?

I used an external usb 2.0 hdd to play this file.

I still think a 35Mbit/sec MPEG-2 file is way out of the ordinary…  You’re killing the box with that kind of required bandwidth.


#5

35 Mb is actually only about 3.5 MBs.

Might be looking at two different things, Bill.

I was noticing:

File size : 17,1 GB
Overall bit rate : 18,9 Mb/s
Bit rate : 18,1 Mb/s
Nominal bit rate : 35,0 Mb/s

Just the nominal bit rate being 35.0 Mb/s is astounding…

So over a 2 hour duration, the AVERAGE is 18.1 to 18.9, but the nominal encoded BW is 35 Mb/sec…

Ick.
