Se: The Green Button - LiveTV Quality - A Fix?

 

Utdraget jeg brukte:

Now that your settings will save you can use GraphEdit to make some changes. Using GraphEdit, go to: Graph > Insert Filters > Multiplexer Devices > Hauppauge WinTV PVR PCI II Encoder and Insert Filter. Then right click on the filter and select properties. Under the "Hauppauge ECP Video" tab change the Bitrate Average to "6000", the Peak to "12000" and P Spacing to "1". Then under the "Dynamic Noise Reduction" tab i changed the "Temporal Static Level" to 0. Try changing this to something between 0 and 3, so see what looks best for your system.

 

You can also adjust the sharpness of you Hauppauge WinTV card, although i find the default setting is fine. With the current drivers the default settings is 4.

 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hcwPP2\DriverData]

"HcwSharpness"= "4"  note* the default setting may be different.

 

Okay one more setting, search through your registry for "DefAvgBitRate". Increasing the Decimal value for this registry setting seems to make a big difference in picture quality. The default settings is something like "20000000", try settings this value to "85000000" or even higher. I've actually set this value to as high as "850000000" count the zeros, and the picture quality got significantly better. I suggest trying to find the highest value your computer will handle without any problems.

 

I hope this helps some of you out there.  I can now watch Live TV and Recordings on a 57" HDTV without any noticeable loss of quality. Here's a screenshot.

Synes absolutt dette funket fo min del. Alternativene er ikke helt like, dette skyldes sikkert to faktorer; jeg har PVR-350 og nyere drivere.

 

Dersom du bruker MediaPortal kan du endre bitrate i setup -> TV-card

Spill av TV i minimert MP med PureVideo dekoderen for å sjekke om bitrate endringene virker.
