HD channels video stuttering and artefacts, sounds issues

[Fulco]

I have two systems:

The Vista system functions perfectly: Watching and recording up to 3 channels (including HD channels) simultaneously results in recordings with no more than 2 errors (in file.txt/log ). HD channels, with CoreAVC (1.6), are absolutely perfect.

 

The new Windows 7 system has serious issues with HD channels (BBD HD; ITV HD, ZDF HD, Das Erste HD, arte HD). MPEG channels are fine.

Cyberlink (PDVD9) Video Decoder (Miscellaneous: DXVA; Video Mode: Auto Select): video, especially on ‘moving’ parts is blocky; video stuttering.

CoreAVC Decoder: video issues (see PDVD9) and sound stuttering/dropping out.

Fullscreen seems even worse.

CoreAVC (2.0): DVB Source: Discontinuities

Cyberlink: DVB Source: no Discontinuities

 

DVBViewer: 4.3.1.115 beta (I started testing the Windows 7 system, with beta 4.3.1.103)

Priority ‘higher than normal’ or ’high’.

Custom Renderer; EVR Custom Video renderer OR VMR9 Video Mixing Renderer.

ATI Catalyst Control Center: ‘Basic Quality’: ‘Use automatic deinterlacing and ‘Pulldown detection’.

 

A (possible) factor:

The ASUS HDAV 1.3 drivers cause a large increase in the system Latency (> 500 us, with spikes > 3000 us every few seconds). This has a visible effect when playing DVB-S2 HD video.

Removing the ASUS HDAV 1.3, and using the SoundMax audio instead, gives a far better picture quality.

Disabling ‘Dolby Digital Life’ / ‘DTS Interactive’ using PCM (with HDAV 1.3 installed), also gives a lower Latency (< 300 us), and better video quality. The sound-stuttering (with CoreAVC) is still there. PCM output also gives some pop-sounds.

first try the normal Version, don't start with BETAS!
