amanzi: I've been batting with an issue I've had over the last few days with certain Freeview channels getting scambled (mixture of green screen and/or blocky images.)

After reading this thread, I'm thinking that the prolem must be coming from the onboard HDMI port with the ATI drivers. Has anyone got recommendations to fixing the issue? I don't really want to put the Nvidia graphics card back in the HTPC as I'd prefer to use the onboard HDMI port.

Afraid to say, the onboard HD3200 can be a bit patchy. Does anyone have a working version of win 7 with HD3200 working?

Sorry, haven't got Win7 so can't really offer to much advice although I will tell people how the recipe for my own system (Win XP).

I have a Gigabyte GA-MA78GM-S2H (Rev1.1) and found the gigabyte drivers worked better than ATI's (for me anyhow).
Basically:
Installed just the Gigabyte driver for HD3200 (no ATI CCC or any of the extra stuff). Using this I get channels with an occasional screen-flash that is pixelated. So basically, quite hard to watch.
Overwrote the Gigabyte driver with the ATI 8.12 CCC drivers (can't install anything later currently as all the 9.X versions disable Hardware acceleration). This gets me all the channels but

TV3 is jumpy- slowing down, speeding up and doing little jumps/skips

C4 is washed out and shows grainy lines

Then I reinstalled the driver from gigabyte overtop ATI's (kept same CCC, just the graphics driver changed)
Presto, all channels work well, no jumping etc. For me, this combo works well (using Powerdvd 8 codec for TV H.264 and hardware accel).

Also, I have tried installing ffdshow and other 3rd party applications, but this often leaves me with the green blocks issue so now I have only the drivers I need.

So basically the things I have installed to get onboard HD3200 working with mediaportal:

PowerDVD8 (hardware accel enabled)

ATI 8.12 CCC, graphics driver overwritten by..

Gigabyte version of graphics drivers installed overtop of ATI 8.12 graphics drivers

There was a lot of trying new drivers/combinations but this method works well for me and the results are repeatable.

Well, using the PCM h.264 codec from powercinema 6, playback seems ok in mediaportal 1.0.1, this is with Catalyst 9.4 on vista 32 sp1.

My issues seem to be at signal related, as I can have long periods of good TV. Signal quality can drop briefly from 100% to <10% though which appears to be the cause of glitches.

Update on my setup.

Removing my amplifier from my aerial improved my reception a fair bit. Now I just have one cable direct to the UHF aerial for raw signal. I still get occasional dropoffs, but these don't seem to be as frequent or as severe as before the aerial mods. TV3 is near perfect, TV1 & 2 have a few more glitches.

I managed to get MediaPortal working well for TV, using the MPC Video Decoder referenced in the AVS Forum mediaportal install thread. I reverted back to Media Portal 1.0, due to 1.0.1's inability of to delete recorded TV. The problems with 1.0.1 that necessitate a quick 1.0.2 release were too much for me.

I am using xmltv listings from nzxmltv with mediaportal for the guide.

Getting there...

Hey nothing wrong with your setup, and you can build a great freeview mediaportal setup using onboard hd3200.

I suggest you go back to XP clean format and use

XP SP3 with latest updates
Latest HVR2200 driver from the UK website
Realtek audio driver
ATI SUITE 8.12
Manually register MPCVideoDec.ax from X86 version of MPC-HC standalone filters.
(I use version - mpchc_x86_v1.2.908.0_MPCVideoDec)
PDVD8 Build 2217aU
Install mkv splitter with default options
MP 1.0 Final
DVBFIX for mediaportal

*** NO OTHER CODECS OR CODEC PACKAGES INSTALLED INCL FFDSHOW ETC.. ***

Make sure ATI refresh rate is set to 50Hz. This will give you smooth as Live HDTV and will do hardware acceleration of all your compliant HD mkv files. If you want to add support for flash video etc, i suggest you manually register the filters rather than installing any packs.

I can definitely see the potential. Right now I'm enjoying TV3 HD, and it is VERY nice. No glitches at all.

I spoke too soon about MP1.0 and the MPC Decoder, when I removed PowerCinema6, MP1.0 reverted to a black screen! Unexpected, as MP was not directly using any Cyberlink codecs, but I recovered by reinstalling PCM6. Phew! Video back in MP!

My current soft set up:

Vista 32 SP1 + all updates
Latest March 09 DirectX install
Latest HVR2200 driver from Windows update
iMon 7.4
ATI Catalyst 9.4
Realtek audio drivers from Gigabyte
MPC Decoder, manually registered
PowerDVD 7.3 BD edition for bluray (what came with LG GGC-H20L +)
PowerCinema6 (upgraded from PCM5.1 that came with HVR2200)
monogram aac driver

What is the DVBFix for mediaportal? I don't seem to need it...

Currently, I use PDVD for bluray, PowerCinema for DVD, and MP for TV. PDVD is the only thing that plays blurays, Powercinema does a much better job of DVD playback than either PDVD or MP, and MP has the best TV guide (via xmltv).

I am really liking the shift from analogue/stereo to Digital HD/5.1 sound. Oooo.

Seriously, this is fabulous quality.

Hmmm. My setup defaults to 60Hz, with no obvious issues. Why 50Hz?

PAL HDTV here is 50 frames per secound, so it's better if your video card is set to output at 50 frames per secound ie. 50Hz

Latest version of MP utilizes dynamic refresh rate changer, it detects the fps of the source and changes your refresh rate to match.

Watch a 720P movie (which by all likelyhood will be 24fps) , set your display to 60Hz then watch a panning scene, then set to 24Hz and then rewatch, you will notice that at 60Hz its slightly jerky. If you can't tell the difference then don't worry just use what ever you like.

Just tried watching a recorded wtv file of Freeview HD channel on a Gigabyte 780G motherboard and it worked fine CPU <10%, just using the drivers that win 7 installed. Are other people having success?

I can report success for hardware accelerated freeview hd on Vista-32 SP1, Catalyst 9.4.

Software is Mediaportal 1.0, MPC Decoder and Powercinema 6 for a helping hand.

I can also report h264 hardware acceleration working with XP SP3, Catalyst 9.4 in both MPC-HC (Internal Filters) and MP Live HDTV (PDVD8). Didn't test for mpeg2 hardware acceleration. However i get the occasional codec glitch/crash with 1080i Live TV3, such that i prefer to stick with 8.12 for XP.

FYI - Mediaportal is not using the MPC Video decoder for h264 for live TV (even if you selected it within MP setup). If you use graphedit you will see that it is using a different h264 codec despite you selecting MPCVideoDec. This is a known problem with MP live tv .ts reader. I can do the same on my system, if i select use MPC Video Decoder for live TV, then run graphedit i can see it reverts back to the PDVD h264 directshow filter.

Hi

I also have a 780G and have been trying to get Freeview working under Win 7.
Green, pixelated or no picture on some channels in Media Centre.

Advice was to install Mediaportal and PowerDVD6.
Mediaportal is installed but is not working properly. It is very slow and is locking up. Have no idea why.
It also is not detecting my Hauppauge USB tuner.
I'm thinking installing PowerDVD is not going to fix these problems :)
Running ATI Catalyst 9.5 driver only.

Don't know where to from here ... any suggestions?
