Graphics card recomendation Full H264 acceleration

Hi,

 

Can anyone recommend a graphics card which will offer full h264 hardware acceleration for use with DVBViewer. It must have dual DVI ports and be under £60. I'm currently looking at an ATI 3650 or Nvidia 8500. Anybody got any personal recommendations? I'm trading in my Nvidia 7900GTO which just seems to struggle a little without full acceleration.

 

Thanks. ;)

I am done with nVIDIA. Have both, a nVIDIA 8600 GTS and an ATi HD 3650. The HD 3650 is way better! 8500 is bad anyway, it has all the nVIDIA VMR/EVR-Bugs and also weak shader performance which degrades deinterlacing quality.

Hi, do you get smooth h264 viewing with the ATI HD 3650? I need to be able to use the dual screen feature to feed my 26" Samsung HDTV without the jerkiness of the the Nvidia card.

Running Dual-Display too (extended desktop). No problems here with a 720p projector at least. Dual-Display support seems better with ATi anyway. If I switch on the projector, Dual-Display is automatically enabled. With nVIDIA I had to restart the PC first to then be able to manually enable the extended desktop option (under XP at least, under Vista the nVIDIA driver seems to do a better job than under XP).

Hi,

 

SAPPHIRE's (ATI) 2600XT HD card with Cyberlink PowerDVD-8 H264 codec works fine for me - however, the 2600 card has only one DVI port and one Analogue VGA port.

 

With this card, my 2.8GHz Athlon processor runs under 50% on HD sources, eg BBC HD, thanks to the 2600 card taking the processing strain!

I have a 2600 XT GDDR4 pci-e with dual DVI, works fine in vista with two displays. With HA and h.264 cpu usage ~ 10-15%. I also tested 8600gt GDDR3, works fine too, but it doesn't have as good picture quality as with ati and no full hardware VC-1 processing. Also with 8600GT OSD quality is rubbish with high-res osd skins (EVR). However 8600GT has one advance: It can handle canal digital nordic h.264 streams which seems to be something off-standard, 2600XT can't handle those without problems. 2600XT breaks the video stream to blocky mess when changing channels, or using timeshift (does happen also with humax 2000 set top box). :)

I have a 8500GT and I can watch BBC HD or ITV HD with a CPU usage of 1 or 2% using PowerDVD decoder. This is using overlay and WindowsXP. I'm not using this computer for anything else than running DVBViewer so i don't really care about shaders or 3D performance of the card...

I've got 2600 Pro on AGP. It's 2xDVI and no D-SUB.

 

CPU usage is 10-12% on HD.

What drivers are you using?

 

Thanks

Right now it's 8.4 AGP Hotfix (tried 8.5 but unstable for me).

Now i looked in task manager and dvdviewer uses only 2-5%. Rest is other processes working in background.

I'm watching ORF HD and Astra HD promo at 25-35% CPU usage. It's using Cyberlink codec + Vista 32bits (EVR).

 

My card is an ATI 3850HD 512mb DDR3. My CPU is AMD64 3800X2

 

 

Is 25-35% too much?

 

I've noticed worse H264 perfomance in Overlay mode.

Anybody using the ATI HD3650 for watching Nordic Canal Digital HD? I curently use the 8500, no problems with CD HD-channels except the TV 2 Sport HD, but the overall quality is below my expectations.

I am using a 2600XT and it works really well on TV 2 Sport HD1 and HD2

Quality is not that great, expected better since it is 720p 50fps

 

On my other PC I needed to upgrade to the lastest PowerDVD 7.3 patch

to get fluid motion.
