Tuner no longer available error when changing channels in Live TV

[ctbaker]

My HTPC is running Windows 7 64-bit, NextPVR v3.2.9 and using a Hauppauge HD-PVR. My Client PC is running Windows 7 64-bit with XBMC 13.2 and the NextPVR plugin v1.9.8

When tuning channels in Live TV, I get a Tuner no longer available error in XBMC. If I start LiveTV on the same channel it was last on, the recording works fine but if I then change channels or the first channel I pick in Live TV requires a channel change then I get the Tuner no longer available error. Recordings are saved on a local drive to the HTPC that is shared over the network to my Client PC.

When using the NextPVR interface directly on my HTPC, it will tune channels on Live TV without giving any errors at all. I have found and tried using two other NShared.DLL files found on these forums to address the issue but there was no improvement. I have also rebuilt the PVR and EPG databases in XBMC without any improvements. Recordings made from the EPG (not live tv) appear to tune the channel without any issues.

I have attached log files from XBMC and NextPVR for review.

UPDATE: I installed XBMC latest nightly build of 14.0 (Kodi) and it shows the NextPVR plugin at v1.9.11 but overall result is still the same.

UPDATE 2: Installed latest drivers to HD PVR and it appeared to solve the problem but it has since returned.

Thank you for helping!

You should never use old dlls.

For some reason data delivery from HDPVR/Colossus stops perhaps during tuning,

and this looks like the five second lease fails near the same time
