Even though I'd prefer to use an Nvidia card for a new htpc I'm building...I want a silent (fanless) card that is also low profile; it seems no such thing exists in the Nvidia camp so I'm wonding can some confirm without a shadow of a doubt that the ATI HD3450 can do hardware based freeview dvb-t decoding with the PowerDVD codec under Vista EVR?

This is the exact card I'm looking at:

And if that won't do what abou the HD4350:

Yes, the HD3450 can, but only upto certain resolutions. 1680x1050 is fine, but 1920x1080 is not.

The HD4350 suffers the same problem.

The Radeon HD4550 is capable of full hardware acceleration at 1920x1080p on 2 displays.

There is a Sapphire HD4550 available that is passive, with DVI, HDMI and VGA outputs. It also includes the low profile bracket. I had to beg the supplier to bring them in after they dropped the non-passive HD4550 from their range entirely.

Great thanks for that! Anyone else know of any other low profile silent cards capable of Freeview?

I have this low profile card http://www.leadtek.com.tw/eng/3d_graphic/overview.asp?lineid=1&pronameid=381

Its an 8500gt tdh hdmi. works great. I guess the only issue is that it is hot, hot, hot, like 80 degrees when its working, so you need to ventilate your case well.

I too use the 8500gt tdh hdmi. It is a half height card and seems to handle freeview HD okay. Tried the 4350 but immediately struck the standard ATI problems with blockiness and green-screen so back it went.

I have the Sapphire HD 4550, it runs 720p and 1080i great - usually about 50C under load. I have 2x 120mm (42cfm) fans blowing air out from the side of the case, about 15cm from the video card.

I'm using the PowerDVD8 codec with hardware acceleration turned on, it requires very little CPU usage.

Hi there, can anyone put me straight on this DVB-T hardware acceleration thing?
What I'm doing is recording the odd Freeview show via my Avermedia card which produces a MP4 file. Playback of this MP4 file via MPC or even the junk Avermedia software causes a huge increase in cpu useage on this thread, most notably with TV3 (obviously). The laptop that I use for this has only a Nvidia GO7600 (M) video card. If I upgrade to a laptop with say 9600GT video, will this cpu useage drop considerably, without any other software, drivers, applications etc.

The software player you are using has to know how to leverage the hardware for decoding.

Have a go with Media Player Classic HC

I just dont get why these cards are so hot when doing h264, whereas a dse/jc matthews settop barely gets above ambient without any fans at all.

Does anyone make a card without all the unneeded 3d stuff, but with h264 support as found in a settop box or similar?

Hi Ragnor

I'm using MPC HC now. Are you saying that MPC HC can ulitilise h.264 avc hardware decoding if it's available on the video card?

Hi Ragnor,

cheers for that link. As I suspected, nvidia 8x/9x cards only. So that'll be a good excuse to upgrade
