No video or audio on any channel live or recorded

[typoknig]

I just installed my HDHomeRun Prime box. In the HDHomeRun Prime configuration NextPVR is selected as the main application. I can watch TV just fine from the HDHomeRun Quick TV application and can watch and record TV from Windows Media Center.

In NPVR under "Settings -> Devices" I have 9 entries, ATSC, QAM, and HDHR for tuners 0, 1, and 2. ATSC and QAM detect no channels during a scan, but HDHR detects 269 channels. In the same dialog the server name is set to the name of my computer which is "MAIN" and database share is set to "\\MAIN\Users\Public\NPVR" which is shared to everyone.

Under "Settings -> Misc" my buffer directory is set to C:\TV and when I try to watch live tv a file will be created in this directory, but it is always 0 bytes in size.
Under "Settings -> Recording" the default recording directory is set to "C:\Recorded TV". When I try to record a channel a file is created in that directory, but it is always 0 bytes in size.
Under "Settings -> Decoders" I have tried every combination of renders and decoders but I always get the same result, no video or audio for live or recorded tv.

I have been messing with this for 2 days now and I'm at a loss. Any direction would be appreciated.

Did you open your firewall to allow necord.exe, ndigitalhost.exe and nextpvr.exe out on your local LAN?

Ugh, thought the firewall was off, but it wasn't... stand by.

In same exact boat, same config, same behavior. However, I just allowed ndigitalhost.exe thru the firewall and that got me 19 seconds of video in file live-WABC-DT-8317.ts. Entire time nPVR app is frozen on screen with ...please wait... and the only way to close it is to kill it in the task manager. Here are two relevant log entries.

This log generally looks ok, and given you're seeing some video, I'm inclined to think your problem just be a playback issue relating to decoders. Can you post your npvr.log?

[scoot]

You are indeed correct! Switched to Microsoft DTV-DVD Video Decoder from ffdshow and the picture appeared. Sound was recorded but no sound from Live TV. Presumably another decoder setting to figure out.

Installed AC3filter and used that. All working.
