Best picture quality in Vista with Gigabyte GA-MA78GM-S2H (2 Viewers)

[doornjoostje]

1st of all, again for your your reply!

as far as I know and tried myself HT 2.0 is enough for good SD deinterlacing. You need HT 3.0 only for HD (only for 1080i). I doubt that a Phenom would bring better SD quality.

Thanks for that info. Almost spent 130 euro.

For SD I wouldn´t buy a Phenom. If you can, you should wait for the new generation of AMDs. Maybe there will be a cheap mainstream X2 with HT3.0, with 45 nm production with lowest energy consumption.

My experience is that the best picture quality can be achieved with hardware acceleration. It is miles better than the best software based decoding (tried ATi mpg2 and Cyberlink without HWAcc against Cyberlink+HWacc; ATi HD3200).

DirectShow filter control -> PowerDVD 8 decoder settings -> MPEG-2 Video Decoder Settings -> Enable "Use hardware accelation" or set it somewhere else?

yes. And don´t forget to select the PDVD8 MPG2 codec in MP settings for TV, Movie and DVD (Cyberlink SP BD-HD Decoder or SP Decoder, under DVD uncheck checkbox "turn off DXVA"). Don´t forget to select EVR under "video renderer settings"! (VMR is not good for DXVA under Vista).

All my settings are like that, only missing DVD uncheck checkbox "turn off DXVA". But this doesn't apply to SD-TV right?
I might try a clean install.

I found the problem. Now I have a smooth picture too.
The Power DVD 8.1.xxxx version I used wasn't working well.
Downloaded a 7.3 version and the picture is as smooth as silk.
Going to make a image of the current situation.

This weekend will do a clean install of windows vista sp1 32 bit.
Make a image with nothing installed except ghost.
Then make an image with all the drivers installed and all the windows updates atm.
Then an image with RC3 installed.
This way I'm very flexible in changing anything for the next time.

everbody for their time.

Under Windows Vista you can also use vector adaptive deinterlacing with the 780G without a HT3.0 cpu. You must edit the registry to make this possible:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{GUID}\0000\UMD\DXVA]
"vforcedeint"="6"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{GUID}\0001\UMD\DXVA]
"vforcedeint"="6"

The "{GUID}" must match with your system. After a reboot you can change the deinterlace method in CCC to VA.

It works great for SD Picture.

Bye,
Nico

Nico.
Going to try this tonight.
Tried in on powerDVD version 8.1, didn't really help me.
But I'm sure it will with the 7.3 version.

This tool (mentioned on the 1st page) makes your life easy:
http://bluesky23.hp.infoseek.co.jp/dxvac/DXVAChecker_1.9.0.0.zip

How to use:
Select a random line, right click -> video accelation settings -> enable vforcedeint and set to 6.
Also set this one for better colors in SD:
Video Acceleration Settings -> search for UseBT601CSC and enable [set to 1]).

Thanks for the link.
It works with PowerDVD8 Codec for me.

I tried the above suggestions and whilst the option to use vector adaptive is now there unfortunately the picture is unwatchable as it stutters very badly, i have a dual core 2.7ghz x64 processor and it is being used at only 20%, any suggestions how to get vector adaptive working and watchable?

What driver version do you use?

hi, I'm using catalyst 8.10. The motion adaptive works fine, just the vector adaptive that appears to be "overloading" something when watching 1080i at 1280 x 720 resolution. Is there any way i can monitor the GPU's performance?
