Failed to build digital preview graph
« on: June 07, 2015, 02:47:37 am »

2. NEW: Option to start digital (ATSC, DVB, and CableCARD) channels in non-time-shifting mode.

When I try this I get the error:

Something went wrong with playback.

What tuner device do you have?

Does it work if you start playing in time-shifting mode, and then use right-click menu to switch to non-time-shifting mode?

Using HD Homerun. Works fine in time shifting but I get the error when trying to watch in non-timeshifting. Didn't know about the right click thing but I just tried it while in time shifting mode and I get the error.

Strange.  I have HDHomeRun and do not have any problem with it.

Please turn on logging and forward me a log after repeating the problem.  yaobing at jriver dot com

Do you use Red October Standard or HQ?  From the log I see some inconsistency.  The DirectShow graph that was built indicates EVR was used, but we ended up in a block of code for non-EVR video renderers.  That in turn returned an error code.

I think I found the problem, and you can help confirm it.

Run RegEdit, and navigate to HKEY_CURRENT_USER\Software\JRiver\Media Center 20\Playback Engine\DirectX Playback\, in it you may find keys "Filters", "Zone 1 Filters", etc.  In one of them (or all of them), you will find the value of "VideoRendererFilter" that is not 3.  Change that to 3, or simply delete the value, the problem should be solved.

It was a piece of old code that still checked that registry value unnecessarily.  Thanks for helping getting to the bottom of it.
