Title: Problems playing 720p in 'Fit Window'
Post by: NorCalJason on October 15, 2012, 02:43:34 pm

Hello,

Trying to get this app all sorted out before purchasing...

While watching a 720p video in 'fit window' mode, the screen flickers in and out.  If I set the window mode to 100%, there's no problem.  There's also no problem with 1080p movies.  Just 720 and Fit Window.

I'm using:

Nvidia Integrated Graphics GF9400...
RedOctober(Standard)

After some research, signs point to nvidia drivers.  I'll uninstall and try a fresh set tonight...

Still no change...  I'll try a different driver package...  Sure hope I can get this to work...

Tried many different videos, some have issues, some do not. 

I'm also getting the flicker when using air video while mc17 is running...

Now it's flickering at strange times during a movie (like when the movie gets really dark)...

Sorry guys, I love the picture.  I love the sound.  And a randomly flickering screen makes this product unuseable to me.

Did you try older Nvidia drivers?  Can you test on another PC?

Hi Jim,

I tried the most recent 6 driver packages from Nvidia's website.  I can reliably produce the flicker/flash in each and every driver package.  No difference between versions.

Would you be willing to try MC18?  You can install it side-by-side with MC17.

The reason is that this recent change might be relevant:
18.0.59 (10/12/2012)
Fixed: Stretch mode and aspect ratio overrides were not working properly with EVR.

Thanks.

Of course I'm willing to try it.  I'll give it a shot tonight and report back.   ;D

Okay, well...  In MC18, still have the problem.  BUT, if I don't do hardware acceleration it's fine.

So disabling HW acceleration solves the issue. 

 ;D

I'm running a QX9650, and without HW acceleration it's only using 5-8% cpu power

spoke too soon!

At the end of a video last night, MC18 started going into a panic.  Rapid screen flashes.  The display flickering on and off, rendering the computer nearly useless.

I also happened to notice the cpu load was doing crazy stuff.  30%, 0%, 30%, 0%, etc...  A force quit is what it took to do anything at all...

The fluctuating CPU load could be anything.  A virus checker, for example.

The flashing is something a loose cable could cause.

It would be worth trying Red October HQ.  It may not work, but you might learn something.

Hi Jim,

The cpu load fluctuation stopped immediatley when I closed MC18.

I'm currently using the integrated graphics on the motherboard.  I do have a discrete card available.  I think I'll try that tonight and see if it works right then...

BTW...  RedOctober HQ currently causes tons of dropped frames...

That's what you would expect if it was a virus checker.

The dropped frames with ROHQ is probably just not enough CPU horsepower.

Test on another PC if you can.  Just as a test.

Hi Jim,

I'm running a quad core Intel 3ghz chip, with 12mb of cache.

I'm not anywhere a CPU bottleneck.

Well..  now using ATI video card.  Working fine.  I can now even do ROHQ.
