690G/x1250 Problems with Vista32 (1 Viewer)

[markuspop]

Hello,

after struggling with the known issues with MP and the Xpress 1250 graphics
chipset I decided to go for Vista 32, because I found many positive feedback
about Vista on such an chipset/graphics card. I'm running a P2-M2A690G box from Asus.

I did a fresh install of Vista 32 Ultimate with SP1 on top of it and all actual
drivers for the barebone as well as the SkyStar2 DVB-S card. No other software
besides the OpSystem, SkyStar2 and MP is installed.

Installation of all went quite well, but watching TV with MP is a bad experience.
The preview window shows stuttering video, sometimes distorted audio. In full
screen mode the video stuttering ist not visible, but often I end up with a
black screen after switching channels ! Audio distortion (kind of clicking) is
also present in full screen mode.
Additionally browsing through the TV menu is terrible slow (much slower then under
XP) (this points me to some problem related with DVB-decoding).

Changing the TV video and audio codecs (tried: MPV/A, DScaler, PowerDVD7 Codecs,
Microsoft preinstalled, ...) seemes to influence the problem. PowerDVD codecs make
it worse, MPV better, but problems with all the codecs.

Note, all the hardware works fine with XP, besides the known problems with
this chipset and MP, so I do not expect any hardware issues.

I searched the forum, but can't find such problems specific to a Vista 32
installation. There are topics on such failures, but not Vista related and
in case of my hardware there seems no special issues with Vista.

Does anybody have the same experience ? Any solutions would be appreciated,
seeing these problems I really think about going back to XP. Compared with
that, the "flipy problem" is really a minor one ;-)

Thanks,
Markus

EVR or VMR9 changing between these, is there no improvement seen.

Not an ATI guy so that's as far as i can go on troubleshooting this.

Hi markus,

I have also some trouble with wrong video AND audio settings.

My Problem similar to yours
Deinterlacing
- HW-deinterlacing ist enabled (maybe by PowerDVD7)
- MP deinterlacing <> none
--> I've can only switch channel 2-3 times then MP hangs (with all codecs)
Please test MP deinterlacing setting = None
Is now working for me, but deinterlacing is not so good as it should be.

An other issue was
wrong audio settings, for SPDIF optical
- audio-driver: SPDIF ist not default
- MP Audio: use "SPDIF optical out"
--> MP hangs after a while
correct:
- audio: SPDIF optical out is default (not HDMI)
- MP Audio: use "defaul DirectSound device"


I'm using EVR.
I dont know my other settings. Can look at it when i'm at home and my girlfriend sleep ;-)
But I didnt found the best settings and have not time to tweak more.


Regards
Starburst

Hi,
thanks for your responses.

Even with deinterlacing turned off I get these problems. Maybe a little less, but not really a big difference.

But as Ray said, I just learned about Vista's EVR, I will try turning it on and off - but where do I do this ?

Thanks, Markus

Hello,

thank you for the hint with EVR, that solved my problem !

I turned off EVR, activated VMR9 and hardware decoding in the Cyberlink PowerDVD7 codec.
This gives a good picture with only around 6-8% CPU load.

Thanks,
Markus
