Checked the TV3 HD programs for the first time today & was surprised by the differences between "Home and Away" vs "So You Think You Can Dance Australia" & "Rove".

Latter two display near perfectly (maybe the occasional dropped frame?), but "Home and Away" showed very noticeable "de-interlacing effects" whenever there was more than slow motion; ie. very distinct offset shaddow images - also, picture broke up a number of times.

Anyone else noticed differences between these programs?

Possible reasons?

(PowerCinema / HVR-4000 / 8600gts / quad core CPU. CPU usage ~25% across all 4 cores - temp ~35deg. GPU temp ~48deg in both instances, so system was far form struggling?)

I would check you have hardware acceleration enabled that very high cpu usage.
Assuming you mean each core was working at 25%

IIRC the 8600gts is not the latest gen GPU & does not handle all the H.264 decoding?

Hm. Maybe I misunderstood. I thought that PowerCinema automatically used hardware acceleration if available. Cannot find any setting in PowerCinema to specifically enable it.

Do I in fact need to specifically enable it?

If so, how / where?

From which program? I cannot see a "Tools" option in either PowerCinema or the NVIDIA Control Panel.

On Media Portal it is in Setup/DirectShow Fitler Control/PowerDVD 7 Decoder setting. Also check the Video renderer the EVR uses less CPU (2%) but seems to break up more and looses synchronisation between audio and video, VMR9 uses around 10-20% and no hardware acceleration is around 50% for my Asus G2S (8600GT M). Have upgraded the NVidia video driver to get the hardware acceleration to work in the first place and now up to version 174.31 to loose most of the de-interlacing problems. But more tinkering to do...

Is this a bit of speculation or a recalled fact?
I've got a similar setup in my second PC with Q6600 and back to an 8600GTS running GBPVR on vista and it has no problem with TV3 DVB-T HD, not any that I can spot anyway?

I'm just a crazy newbie?

8600GTS core is not the latest GPU because of course it has been supplanted by the 8800GT and 9xxx series cards, all of which sport the same core architecture.

HOWEVER, the 8400/8500/8600 cards all fully support hardware H.264 decoding, unlike the 6xxx or 7xxx series cards.
