Unhandled exception when trying to tune.

[GeoC]

I recently installed a fresh copy of Windows XP on a Pentium 4 system and and fully updated it to SP3. I then installed NPVR as the only appliction and a SkyStar2 + BDA driver and all appeared OK initially - apart from a disecq issue, but it did tune ok and produce video and audio. However after a reboot, it now won't tune, crashing straight away with:
Unexpected error in scanning form:System.NullReferenceException: Object reference not set to an instance of an object. - please see attached log file.

Also, if I try to view live TV from the menu, it immediately crashes with a popup window saying " Unhandled exception has occured in a component in your application........Index was out of range...."

I've reinstalled NPVR and C++ runtimes several times now, but no difference.

Does anyone have any ideas please?

It's unable to find the Microsoft Demultiplexer on your machine. It needs this to function. This is normally present on all Windows machines, but we have seen a couple of apps in the past that deregister this component when they're uninstalled.

Thanks for the reply, Sub - how do I re-register the MS Demultiplexer?

I think you can just run: regsvr32 c:\windows\system32\mpg2splt.ax

OK - thanks - I just found it, and it now scans for channels.
