I finally figured out the thing.
First issue was no video on outdoor channel HD using dvbworld software:
Ok, someone mentioned to check the apid and you are right. It wouldn't show a picture unless the apid was correct. Still maxed out the system.
Next issue: 100% CPU usage on HD channels.
I FINALLY GOT IT TO WORK BEAUTIFULLY! 40-55% or so CPU usage on HD content.
Here's what I did to get HD working on my system.
According to DCCheck(free app from Micro$oft) which is an app that monitors your installed codecs, the nVidia PureVideo codec was my system's default codec. Apparently, DVBWorld was deciding to NOT use this. There's no way that I could find to tell DVB world to use it. No ini files floating around, no menu item for it, zip zero zilch.
Started to browse around the dvbworld folder and decided to start removing .ax files from the folder. The theory was that it would not find whatever it is trying to use and then be forced to use the system's default codec which in my case is the PureVideo.
It worked. Delete mpgdec.ax from the dvbworld folder and it will use the system default after that.
Bring on the HD feeds.
