ProgDVB & Vista experience
Posted: Wed Jan 17, 2007 1:28 pm
Generally there is no problem with ProgDVB on Twinhan WDM drivers and NVidia/Cyberlink decoders when ProgDVB is displayed on the first monitor.
Today NVidia Vista driver doesn't support fullscreen video on secondary monitor (tv-out), so ProgDVB must be run on the second monitor in fullscreen. When Cyberlink 7/NVidia PureVideo doceders are being used ProgDVB freezes for ever (or crash) after channel change. It seems there are some problems when the graph is rebuilt and ProgDVB runs on secondary monitor. It happens with VMR9 renderer. With VMR7 screen scaling is CPU intensive and it seems it is not hardware accalerated. Of course it is not a ProgDVB issue.
I've found that using Vista built-in MPG2 decoder everything works properly on any monitor. This decoder has no GUI for configuration, it perfomrms some nice deinterlacing but somtimes it flickers. At least it works on secondary monitor. I'm waiting for NVidia full-featured driver which supports clone-mode with fullscreen video option. For now even clone mode limits you to use tv-out resolution on the primiary monitor, which is awful (you can use at most 1024x768). The problem is that panning the screen on tv-out is not working yet in the driver.
I can use both Cyberlink 7/NVidia decoders with some other DVBS software under Vista (on any monitor) without major problems, so it seems that ProgDVB could be easily fixed to fully support Vista.
