LiveTV preview blank screen

[DarrenJ]

I've upgraded to 1.4.7 and I'm finding that if I turn on Live Preview, then I get about 1 second of picture, then a blank screen.

If I turn Live Preview off, then everything is fine...recordings, livetv, etc. Except when I am watching one channel and another recording, that is scheduled, starts, then the picture is interupted by a blank screen for about 0.5 to 1 second. It usually happens when its close to a cliffhanger end of a tv episode :eek: After the 1 second blank screen the picture is back, but sometimes the audio is out of whack slightly.

I figured if I turn on Live Preview in config, then this problem may go away..except it's the opposite. maximum of 1 second of picture, then blank screen as soon as I watch LiveTV I've changed codecs, etc but it made no difference. I restored my previous version of gvpvr and the issue did not happen.

I'm running Win7 32bit with 2 dual tuner NovaT tuners.
I've looked through the logs (attached), but cant see anything. Can anyone offer any ideas?
cheers

Can you see if attached patch makes any difference?

You are the man!
That fixed the Live Preview problem.

Not sure about the blank screen interuption when recordings start in non-Live Preview mode yet, but will find out tonight hopefully.

Cheers!

Unfortunately that isnt a very permanent fix. I'll need to think of someway of making a permanent change that provides this but still works for other users, otherwise you'll find its broken again next time you get a newer version of that file.

What operating system are you running exactly?

Win7 32bit RTM. Didnt test it under RC.
I'm not sure what the fix was, but it's not related to anything like video card drivers? I'm running an XFX 9600GT (nvidia chipset) if that's any help.

Left live preview on this evening, and no blank screen 'outage' when another recording kicked in. I'll test over weekend sometime what happens with live preview off.
