Hi Hellonearth,

A constant 25-30% CPU load is actually a bit high and leads me to believe that the hardware accelaration is not working properly. However, if the CPU load is spiking or pulsing, then it's fine, as my PC does the same thing. You may want to playback some pre-recorded HD content and see what sort of CPU load you get. If it's in the 5-9% range, the hardware accelaration is indeed working properly.

If the CPU load is constant 25-30%, I'd suggest downloading the Cyberlink PowerDVD 8 trial version and using it's supplied H.264 and AAC codecs; instead of the MONOGRAM AAC codec, which I found to be rather poor. I think that one can still use the Cyberlink codecs even after the trial software expires.

If you don't wish to download the entire PowerDVD 8 trial - it's ~100 MB - then the H.264 codec from it can be found at the below URL:

That HD pack sucked or I installed it wrong, it's doesn;t uninstall as well, that sucks...

The quality, sucks, I get blocky like shadows or random boxes around movement.

I think downloading the trial will be less sucks than that HD pack.

You may have done something wrong. I installed it awhile ago and had no problem with the install or uninstall.

It terms of quality, if one opens the Catalyst Control Center and then proceeds to the Avivo Video options, there are various parameters effecting it.

Best

I checked the Avivo settings out, they are set to normal settings, the filters for noise and endge dection some not messasery with digital tv. If the siginal goes, you loose frames, not static.

I got SP1 now and the video recording is good, didn't look at the speed difference as I was happy with the recorded quality, but got the wrong channel as the TV guide bit doesn't work. Still there is a heap of other threads on that.

When I time shift, I use between 15% and 30%, so that's recording and paying at the same time. It's going very nice currently.
Can game and watch tv on the 2nd monitor. no worries.

DVB uses lossy compression. Therefore, while analogue static is not an issue with DVB - unless, of course, one is viewing something that was originally recorded with analogue equipment - the compression used can and will introduce video artifacts that AVIVO HD processing can smooth out or correct.

You were complaining about artifacts, so I thought I'd offer a solution. However, since you seem to have your mind made up about the whole thing, I wont bother with it any more.

Sorry for the confusion. When it was bad it was beyond filters, but it's all working nicely here now. Thanks for the tips.

Going by the screenshots i preferr ATI's look overall to Nvidia's. Do those screenshots represent well the nz freeview hd look from the ati hd3870 and nvidia 9600gt cards?
