HDHR 0-byte file - Clean Win10 OS, Clean NextPVR install

[JavaWiz]

After having great success at upgrading from Win8.1 to Win10 with basically no problems with NextPVR, I decided to acquire a new SSD and do a clean install of Windows 10. I've been able to get the Analog tuner (HVR-2250 working with my XFinity STB), however am having problems with my Silicon Dust HD HomeRun Prime.

I have not done a clean install of OS and NextPVR in awhile, so I suspect I'm missing some step somewhere, but after troubleshooting and scanning wiki and forum have not discovered what is wrong...

Problem:
When tuned to a HDHR channel, NextPVR creates 0-byte files. This is true for LiveTV and Recordings. Experience is a blank screen with no video. However the file gets created in the LiveTV (or Recordings) directory.

Configuration steps:

• Clean Install of Windows 10
  
• Install of most current HDHR drivers and applications
  
• Install of NextPVR (3.4.8)
  
• Install of SoftPVR (HVR-2250 Drivers for Analog connection)
  
• Install of IRBlaster software (from Win-TV install)
  
• Install of K-Lite Codec Pack (i.e. LAV Decoder for mpg2 video)
  
• Install of AC3 Codec (i.e. Audio decoder)
  
• Setup of Analog device successful
  
• Setup/Configure of Tuner0 of HDHR successful (253 channels identified)
  

I have not mapped to my SchedulesDirect listings yet, so TV guide is not populated with data, but channels for both HVR-2250 and HDHR show up.

Behavior:

• Analog channels for LiveTV and Recordings work fine. Channel changes work
  
• When tuning to HDHR channel, black screen, no video, no audio, no apparent errors in log files.
  
• Check HDHR web interface, HDHR is tuning on channel with excellent signal strength, and changing channels when requested.
  

Triage:

• Verified that Firewall was open for NDigitalHost, NextPVR and NRecord (Inbound rules)
  
• Verified that HDHR is available and works on target system via HDHomeRun View Application
  
• Reviewed log files to look for any errors
  
• Attached logs show an example of HDHR problem and successful HVR-2250 for the same channel
  • First channel selection is HDHR - results in zero-byte file and blank video/audio
    
  • Second channel selection is 2250 - results in proper LiveTV
    

I don't believe this is just a codec problem, due to the 0-byte files for HDHR, but regular files when tuning thru the HVR-2250. I should also note, when I did the initial upgrade to Win10, with an exiting install of 3.4.8, all worked fine....

What am I missing????

When you try to view live tv, does the HDHomeRun Config indicate it's streaming data at a valid sounding data rate?

[JavaWiz]

Yes, locked on, good signal, streaming @ 2.6 mbps

Did you try temporarily turning of the firewall completely?

[JavaWiz]

Yes, Firewall off, same result...

If you create a c:\temp directory, and set HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NPVR\RecordFullTS=1, do you get c:\temp\full.ts with valid data in it?

[JavaWiz]

I'm running 32bit, should the key be:
HKEY_LOCAL_MACHINE\SOFTWARE\NPVR\RecordFullTS=1

If so, no, no files get created in C:\temp

Either way (I created the node Wow6432Node) and no files get created.

You should get something. It was really down to whether the file is empty, or has real content.

Did you restart the recording service? Probably needed to.

[JavaWiz]

Ok added key(s)
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NPVR\RecordFullTS=1
and
HKEY_LOCAL_MACHINE\SOFTWARE\NPVR\RecordFullTS=1

Restarted recording service

Attempted to watch Channel 3 again...

No file created in c:\temp

No obvious errors in the log files.


Midnight here. Have meeting @ 5:30am, hitting the sack, I'll pick up in the morning if you have any other suggestions...

I wonder if it's something to do with the permissions of the c:\temp directory?
