Hi Def TV and MCE
« on: 27 November 2007, 12:33:15 »
I think I may need a new MCE  :'(

Started watching (bloody phone kept ringing so didn't see it all the way through) a Hi Def version of Casino Royale last night.  The thing runs at 95% CPU all the way through it. Amazingly, even during fast action scenes, it didn't drop frames, but did twice drop frames for now real reason (presumably Windows doing something else).

Running at 1920 x 1080 resolution, Nvidia 8500GT video, 3.2Ghz P4, 2Gb RAM.  I need more performance  :'(


I was thinking along the lines of a Intel 965 (coz they're cheap, yet still powerful) based board and a Core 2 Quad chip.  Will that be able to handle my needs?

Which HiDef version was this?

Have you considered a DSAT card to use BBC-HD?

if I'm not wrong the problem is neither the cpu nor the RAMs..Possibly theres disk access for some reason..This keep the CPU busy waiting.. a higher RPM disk or a SCSI (requiring a SCSI card also) may solve.. :-/

Edit : Can you see IRQ numbers higher than 15 on system IRQs ..If answer is yes SCSI can be an option ..Otherwise will share IRQ with another card and slow down..

BR obviously, as Casino Royale is distributed by Sony.

Disk access is fine and fast.  You're right, the RAM is OK, though its DDR400, which is getting a bit slow by todays standards.  Its purely CPU by look of it. Fortunately, it looks like it is truely multithreaded decoder (the P4 is hyperthreaded, and its 95% of each 'chip' used), so was hoping the extra cores and better efficiency of a Core 2 Quad would improve the playback....

I think we all know BBC would not pay to transmit decent programmes such as Top Gear in HD

Agree, some of the better documentaries that the BBC will soon stop making would be a bonus, but not enough of a reason to stick a dirty great serving plate on the front of my house...

So what was the source - so we have an idea what decoding is required?

MPEG4, MPEG2 ??

Some video cards AFAIR can carry out MPEG decoding

Dear Santa...

% 95 load  :o   really interesting...only one thing can make a 3.2 CPU this much load..Rendering heavily and the channel for the RAMS or channel to VGA is slow keeping the CPU busy..I see Xeon servers with many SCSI disks and heavy queries from bank branches not reaching even % 40 load..
