Error Unable to Communicate with Recording Service

[ottoguy]

I keep getting two errors when trying to enter Live Tv. "Unable to Communicate with Recording Service" or "Unable to find an available tuner". More often it is the communication with the recording service. This is all on one pc, no mvps, clients, or nmt's. I have 3 tuners, Hauppauge PVR USB2, Hauppauge 250, and Hauppauge 1800. The 250 doesn't work in Windows 7 64 bit so it's not in use. With just the PVR USB2 NPVR works great. However as soon as I put the 1800 in the computer nothing works. I get the above errors. The logs show sometimes an "Attempt to read protected memory" I have ran windows 7 memory test and re-seated the dimms. The same hardware works fine with windows xp and gbpvr. (dual boot). I have turned off windows firewall, and there is no virus protection or other such program running. It is a fresh install of windows with NPVR, and IRServer Suite. Any suggestions would be greatly appreciated. I am running the newest version of NPVR.

The NPVR.log file doesn't show much as right now the program crashes as soon as it opens. The NPVR.log.2 is the last time it ran and I was receiving the communication errors.

You seem to be having problems with the hardware encoders on your device(s), which was addressed by a patch a couple weeks ago. Perhaps you have not applied the latest patch archive? see post 2 in the sticky linked in my signature.

That fixed it. Wish I had see that earlier. I read through the patches, but didn't see any that seemed to apply.

Patch 12 was most likely what fixed your issue. However as explained therein, everyone is supposed to just install the patches first and ask questions later.

Sorry to dig up an old thread, getting the same problem as the original poster, but I've installed all the patches and it still doesn't work. I'm running vista and installed the original app with administrator privileges, I then stopped the nrecord service, unblocked the zip file and extracted over the existing files using vista explorer. The TV capture card is found fine and even scans through and finds all the channels, but when I go to live tv I just get 'Error Unable to Communicate with Recording Service'

Maybe a stupid question, but you did re-start the recording service after you copied over the files didn't you?

Maybe a stupid question, but you did re-start the recording service after you copied over the files didn't you?

And even more important; did you stop recording service prior to copying the patch-files? Some of the .dll's are in use if recording service is running.

[codex]

Yes, stopped service before I copied the patch files (they all copied across over the top of the other files fine), then restarted the service. I've even tried running NPVR as administrator and no luck. Are there any log files that may help (and if so, how do I access them?).

OK, found the logs, this seems to be the important bit:

As far as I can tell the nrecord service seem to be running OK on my machine.

[Reddwarf]

That's a firewall problem, you need to allow Nrecord.exe and NextPVR.exe through the firewall, and maybe open ports 8968 and 8866.
