Unable to start device: Device failed to start

[escapeMCP]

I am trying to upgrade from GBPVR to NPVR. I have stopped everything to do with GBPVR (service & autorun entries). I start NPVR and try to run a scan for channels (settings>devices>highlight tuner>device setup>set country & region>scan), but I get the error shown. I have read through the forums, but could not find a similar problem. I enclose the logs, although I think the problem is here:

Any ideas anyone?? I have tried the "Keep digital graphs constructed" option in the Misc tab of the settings (as it seemed as if it had something to do with graphs), as well as choosing different decoders in the decoders tab, but I am still getting the same problem on both tuners on my Asus DTV card.

Many thanks,

I also don't seem to have any services associated with NVPR... should these be created on install, or are they created only once you have a tuning device up and running?

After install you'd normally have a service called 'NPVR Recording Service'. If you havent got one, then it sounds like something went wrong in the installer. That said, it can run just fine without it. Without it, it'll run up the recording service locally in the NextPVR.exe process.

I cant see any particular reason for your problem, but the device is failing to hook up, resulting in the error when it attempts to start it.

I have sussed out the not scanning problem.... drivers! I have a Asus MyCinema P7131 DUAL card, but Asus have not updated the drivers for about 5 years for this card. They do have drivers for the single tuner card, but these don't install on the dual (it asks you to remove one of the tuners.. a bit of an impossibility when they are both attached to the same bit of hardware!). I manually installed drivers (through Windows dev manager) on each card and it scans like a charm (this is how I installed them before, but I forgot!).
Still no service though. Will it record in the background if NextPVR is stopped? (I am thinking this is a no).
Many thanks for all your hard work on this, sub. I used GBPVR before this for a year or two, and have only just noticed that NPVR has been released in the meantime. Many thanks for your work.

Great!

Thats correct, if NRecord.exe isnt running in the background then you wont get any background recordings etc unless NextPVR.exe is running.

Start a command prompt (with Run As Administrator on Vista/Win7), change to 'c:\program files\npvr', and run "nrecord.exe INSTALL", then reboot.

Many thanks for all your hard work on this, sub. I used GBPVR before this for a year or two, and have only just noticed that NPVR has been released in the meantime. Many thanks for your work.

Cheers.

Hmm... another problem.. live TV crashes within a minute of watching it. I just get a message saying crash dump saved to c:\temp\crash.mdmp. Tried all different decoders without any success in eliminating problem. Haven't searched forums for answer, but if I cannot find one, should I start a new thread?

[sub]

zip and attach the crash.mdmp and I'll take a look.

Looking good. Thinking about the crashdump thingy... would it cause any problems if my system is on drive H: (troubles when installing windows!!)?? I have a "subst c: h:\" running on startup, to give me a drive c: once windows (XP) is starting, but can you see this causing any issues?

Many thanks for all your help sub. I think I'm gonna have to click that donate button when I get paid next

Its crashing in the Microsoft PsisDecd.dll. This is a component Microsoft uses for watching the channel metadata in the currently tuned frequency, and some versions of it had bugs which dont like certain broadcaster data. Its happened to quite a few people over the years, usually XP users, in lots of tv apps. The fix seems to be changing to a different version of PsisDecd.dll.
