Watch HDTV using Hardware Acceleration

Hi All,

I have this graphics card;

Shaphire HD 2600 PRO (AGP)
http://www.sapphiretech.com/us/products/products_overview.php?gpid=180

I want to make full use of the AVIVO hardware accelerations so i can play HDTV on my 2.4Ghz PC.

Having done some reading it looks like i need to enable the AVIVO Hardware Acceleration via a compatitle program.  PowerDVD has the option, but when i check the option nothing happens and when i go back into the option it's unchecked.


There should be several free alternatives, which i'd prefer to use.


Any thoughts on how i get HDTV working on my PC?

Did u mean connecting your PC to a HDTV using HDTV connector or watching HDTV on your PC ?

That power DVD option of enabling HDTV is when you connected your PC to a HDTV using seperate connector. Hope this clarifies your doubts :)

Yes, i am trying to connect my PC to an HDTV.

I was under the impression Hardware Acceleration will reduce the PC CPU usuage.  Is this only for certian files types?

The hardware acceleration would give you better FPS for either playing games or watching movie on ur PC monitor or HDTV. This will work with your CPU for better performance of your system. But incase you are already able to watch the display on HDTV i.e play a movie, I dont think you need to anything further. There are speciifc files which are high DVD quality which allow you to choose that option in power dvd.

Currently my PC CPU is maxed when i watch High quality HD tv and so the video/audio is jerky.

Is there a way to have the graphics card pick up some of the processing so i can watch these files.

+What is FPS?


Thanks

skschandraCommented:
FPS is frames per second.

Alright first you need to bench mark your graphic card performance in 3D Mark software. It is available @ http://downloads.guru3d.com/Benchmarks-&-Demo's_c6.html for download. Here you would know if the graphic card is performing the way its designed to and if not it would tell you probable reasons for the same. Apart from this it would also compare your system with many other systems in the world who have bench marked their systems with similar configs. This way you can check what could be the reason for high CPU usage on HDTV.

If you are watching anything with H.264 encoding (like blu-ray), it may use a software decoder and your cpu to decode it - that may explain why your playback is jerky.  Certain HD content requires a more powerful cpu: http://arstechnica.com/hardware/news/2007/12/measuring-cpu-usage-during-hd-playback-ati-vs-nvidia.ars Perhaps a later version of the video driver may help?

The majority of the HDTV wil be H.264...

I will bench mark the card tonight and let you know how it goes.  I'm not convinced the graphics card is doing any of the CPU processing.

Hello Moderator

I had recommended detox to perform benchmarking on his grafix card using 3rd party software. He is yet to come back on this. Since he has not come back, I assume either the problem is solved as it has already been few months. Why should we not get some points as we helped him to fix the problem ?

I'll download 3D mark and post results.

I can't run 3D mark it hangs with 100% CPU when it starts up.


Is there any other software i can try?


I only need HDTV for movies.

CallandorCommented:
What cpu do you have?  It sounds like it is insufficient, or the video card is not offloading the work if it hangs at 100% right off the bat.

detox1978Author Commented:
The processor is 2.4Ghz...


I've tweaked the settings so i can watch 720, but 1080 max's out the CPU.

From reading around, 2.4Ghz should be fine if the graphic card is running hardware acceleration.

CallandorCommented:
Is this an H.264 encoded movie?  (for example, blu-ray)  I mentioned in my first post that H.264 requires higher end hardware.

detox1978Author Commented:
Harware acceleration enables lower spec machines to run H.264 flawlessly.


I've read several guides for using Windows Media Player Classic and can get it to run 720, but i'm sur ethe card isn't working as it should.

CallandorCommented:
I agree that an HD 2600 should alleviate much of the cpu load.  The only way to know if your video card is working properly is to replace it with one that also has HD decoding.

ok, i've downloaded and run passmark.


What should i be looking for ?

Compare 3D benchmarks to a system that has a similar video card.

Which parts should I be comparing?

detox1978Author Commented:
I've done some further reading and found Media Player Classic Home Cinema, which is pre-tweaked for HD.

http://mpc-hc.sourceforge.net/DXVASupport.html

this runs 720 at around 20% - 40% CPU.


I am now experiencing the random green frames, and it suggests to downgrade

"Warning for ATI users : VC1 acceleration is broken in 8.6 release (green frames appears randomly during playback). If you experiments such trouble, please revert to 8.5 build. "


I have no clue what this means, any suggestions?

3D Graphics Mark

For example, my HD 4850 is just a little slower than the one in the Asus M2A-VM.

I think it means this - version 6.4.8.5

detox1978Author Commented:
I gave version 6.4.8.5 a try, but the CPU shot upto 100%.


Looking at the output filters in Media Player Classic Home Cinema, i have an internal filter called VC1.

Any idea how i can down grade the filter it uses?

Do a search on DirectShow filters - I think that is how they are changed: http://www.codecguide.com/faq_mpc.htm

May be you could try VLCMedia player before trying anyother codecs. VLC uses its internal codecs and will not interfere with the system codecs. So once we check if VLCmedia player works then you can try combination of different codecs.
