I have only recently re installed NPVR on my system which I have now upgraded to Windows 7 64 bit. I have a quad core i3 processor and am using the Intel HD graphics. Everything works fine except that it does not seem to matter what renderer I choose or what codecs, I get perfect sound but no vision in Live TV mode. If I record a program - there is no video when played back on NPVR but perfect performance when played back through VLC.
Any suggestions would be appreciated.
It'll probably be done to the video decoder you're selecting. If you're using DVB-T, then it'll be the H.264 video decoder. Most people either use the Microsoft DTV-DVD Video Decoder or the ArcSoft Video Decoder.
Thank you - I was sure that it had to be in the decoder settings but I have so many on the machine and obviously I didn't try the MS one in that slot. It now works as advertised.
Thankyou again
I was able to play MP4 files until last night. Now I get audio with no video the first time. I select the MP4 file again and NPVR crashes. Attached is my NPVR.log file.

MP4 file used to play until last night, and nothing has changed on my system. DXDIAG says I have DirectX 11 installed.

...sure
When it comes to .mp4 files, NPVR just lets Windows Directshow take care of playback. I'm guessing something has been installed/uninstalled/tweaked causing directshow to choose different decoders.
The logs indicate directshow is picking the following decoders. I'd suspect either the 'Emuzed AAC/AAC+ Decoder TFilter' or 'ffdshow Video Decoder' is causing the problem.

The directx thing wont directly be related to your .mp4 problem, but probably indicates that your machine is unable to find the required directx runtime components, causing it to software renderer the UI instead, leading to higher CPU. You can also get this error if you're testing over remote desktop though, where directx is unavailable.
I installed the latest version of Shark007 codecs and my problem went away. It worked and then stopped working the next day. I did install a few apps, but they weren't related to video in any way.
You can try SAF6 - link below. It will set all automatically for you (including DirectX update).
