Display "waiting" to show next frame + no display output.

[GuruSR]

A while ago, I mentioned that I was seeing a "blank" screen and lately it's a "no signal" while NextPVR is going, the machine is set to sleep but not the display (set to Never), have tried every output method known to NextPVR, made no difference, what happens is, if I pause a recording, a few seconds later when the lower third info window drops out of the way, it advances 1 frame (in most cases you see the picture move). Using the Video section to play back videos also has this same effect. The same situation happens when the machine is brought out of sleep and the TV is turned on, the TV reports "no signal", until I push a key on the remote that causes a draw update on-screen (while in the menu), then the picture returns.

Any possibility to have an "Always On Top" option to enforce keeping NextPVR "active and on top", as sometimes on boot (set to start with the computer), the start bar shows up over it and it's unresponsive to the remote.

Also, if the TV is turned off during playback, causes massive grief with the playback, it causes it to show in a small area in the top right corner of the screen (as if the playback defaulted to 1024x768 or something tiny). Its a downside of pausing a show then grabbing food, coming back to find someone turned the TV "ON" thinking it was off when in fact, they turned it off. Turning it back on, renders the playback stopped and playing it again with a resume puts it into that small area, until you stop it again and then play again. Almost as if it's receiving the screen dimension changes too late.

What video "card"? And is it an HDMI connection?

I ask because I have had similar problems with ATi and Intel video ... I have no problems using Nvidia.

If NextPVR was in windowed mode at the time, do you see the rest of the desktop, with only the NextPVR window black, or is everything black? (ie, trying to determine if this is really anything to do with NextPVR, or more about the video card not being awake)

I remember seeing this in the past with an previous machine. The desktop resolution would resize whenever the monitor was turned off. I remember fixing it with a couple of registry setting changes. A quick google turns up a few articles like:

Sorry, fun (and bloody) day, I.T. can be entertaining and physically painful (love inside of cases where there is stamped metal). The issue with the display going "no signal" happens with the onboard Intel driver, there doesn't seem to be an issue with it, but it seems the display driver is being told not to refresh until an actual display change happens (from the looks of it) and when a major change happens (like the info screen going away), then the display updates. Same goes with the remote and moving the "active selection" somewhere, then the TV sees a signal and comes back on.

When the TV is off, yes, it's going to the "default" screen resolution, but when it comes back on, NextPVR is still full screen, just the playback of the show winds up in small in the top left corner of the screen until I hit *back* on it and then play again. So NextPVR's main window *is* staying at the proper size, but the playback window which was paused when the TV was turned off and back on, isn't.

the TV is connected to the PC via an HDMI switcher, but doesn't interfere with any of the HDMI and is 1.4 compliant (passive), it won't switch ports which have no sync signal, which it sees even when the TV is turned off, but doesn't when the PC is off/asleep.

I'd put those registry settings in, to force it to remember the resolution, which would help with one aspect.

The 'no signal' to your TV is definitely something windows/driver related, and not something NextPVR will have any control over.

FYI, when it comes to the OSD updating within the NextPVR window, what video renderer are you using? Some can only update the OSD when new video frames are being presented. (NextPVR tries to tell it to repaint the current frame, in hopes of getting it to show an OSD change, which is why you sometimes see it appear to jump forward a frame)

I've tried all of the renderers available, even Dx9, didn't matter, same situation happened, in the menus does the same thing. I'll put the registry entries in when I can between remote calls.

What do you mean? Changing the video renderer might only have affected this very specific part of your description:

if I pause a recording, a few seconds later when the lower third info window drops out of the way, it advances 1 frame (in most cases you see the picture move).

ie, I wouldn't expect changing the video renderer to have any effect on Windows resizing your desktop when the monitor is turned off (set those registry settings to stop your machine doing this). It also wouldn't have any effect on Windows or your drivers not waking the HDMI input until you press a key - that is entirely unrelated to NextPVR.
