I setup the my nova-t stick with MediaPortal on the weekend, everything seems working.
However i'm found the cpu usage is around 60% when i watch freeview tv program.
i have an 8600GT card and core duo cpu.

When I use wintv 7 that come with the tv stick to watch tv the cpu usage is around 10%. so it make me think that somehow the mediaportal is not using hardware acceleartion to decode h.264.

the h.264 codec i'm using is the arcsoft one that come with the tv stick.

is there anything that i'm missing in setup?

TIA.

I dont know if the arcsoft hands off the h.264 to the GPU? You might wanna find out.

I use the cyberlink dvd codecs, works well! Though I heard the newer versions don't allow direct access to the codecs anymore.

I thought the arcsoft decoders were one of the two that would offload to GPU, the others being PowerDVD 8.

Is there any other player you can try (not vlc) that uses the same decoders to verify that it's not an MP problem?

arcsoft is supposed to offload to GPU.
If you use Win7/Vista then you must set renderer to EVR to get hardware acceleration. (XP should use VRM9)
if you want to try PDVD codec google "HD PACK 2.2"

How is the TV3 1080i playback with Mediaportal on your system? They changed the rendering some versions back, whcih affected a significant number of MP users as anything below around an NV9400-NV9500 video card would suffer from major stutter.

Wacthing TV3 CPU usage ~70-80%
Watching TV2 HD Program MP CPU usage ~60%
Watching TV3 Plus 1 CPU usage ~25%

I tried with Total Media and the performance is just as bad as MediaPortal.
seems hardware acceleration only work on wintv 7.

dowloaded the HD pack 2.2 and found that the arcsoft driver in the hd pack 2.2 is newer than my one come with the nova-t tv stick.

the new driver works better the cpu usage for MP is less around ~10-15%.

tried the cyberlink driver as well, but it is not as smooth as the arcsoft driver.

thanks everyone for your reply.

glad you got it going. perhaps the free version of arcsoft that came with your nova-tv stick was a dummed down version. The H264 Cyberlink Powercinema codec that comes free with hauppague doesn't do dxva.
