    Multiple crashes on clients

    Since installing the latest version, I have seen quite a number of application errors (crashes with force close) - they most regularly happen after a recording completes and NPVR returns to the GUI, but have also seen them as it sits idling at the recordings, listings, or home display, as it often does. This occurs on two different clients, so while I thought it might be a display or driver issue, I can't imagine it taking place on both units as they are quite a bit different hardware-wise. Did not see these errors on previous versions, and I can accept "close" and relaunch easily without issue - until the next time. - ideas?

    Here is what appear in the Event viewer - these particular two errors took place after I stopped viewing last night:

    (Event ID 1000 Application Error)

    Are you using the TVListings plugin? We've seen a crash like the one above from it in the past. I think it relates to something it's trying to do with animations. If you are running TVListings, you could try running NextPVR with the "-no3d" command line to see if the problem goes away.

    yep, you guessed it. It is the latest version that was set to function with the standard exe recently updated by the author, though I think the error occurred with the separate patch you had provided to npvr.exe previously. I'll try the "-no3d" switch - what do I lose? maybe I need to move this to the TV Listings forum

    Yeah, I remember another TVListings user saying they'd had the problem a while, so I don't think it related to the most recent release.

    Animations are turned off.

    I'll move it for you.

    I'm not a TVListings users, but I do have it installed (for investigating that recent issue). If you know of a set of steps to reproduce the problem, I'll see if I can track down the cause.

    Knowing it happens now relative to TV Listings and the two modules, TV Recordings and TV Listings, I think you can recreate the error buy allowing a recording to complete from the "TV Recordings" screen, and may see intermittent crash as the video player exits to those screens....doesn't happen every time but often enough you can likely see it. I tend to either launch a live show from "TV Listings" custom guide screen, or from "TV Recordings" view. I'd dump the whole thing if I could train the family an the new (and improved) standard screens, and separately, take the time to clean up all the channel mess I have with both ATSC and Cablecard tuners - lotsa duplication I have always avoided by creating custom TV Listings screens

    Sub -did you get a chance to test? Posting in hopes maybe Alibert can look into issue, which did not occur with previous versions for me. Adding the "-no3d" flag solved the crashing issue, but removes the animations, and more importantly, makes the screen updates in the UI quite sluggish in response to remote commands.

    I had a go at reproducing it, but couldn't get the problem to happen.

    Thanks for checking - doing a bit of testing...I turned animations back on, removed the flag, but unchecked "wait for vsync" - early on, no crash yet, and screen far more responsive. What is the potential benefit of the vsync option in "general"? I just got a 4K set and am running at the native 2160 res 60hz, so I think turning the 3d off was an even larger impact than might otherwise be.

    Sub, i am using -no3d and zero crashes. Previously, it would barf quite often after simply watching a recording and then escaping back to the main menu.
