View Full Version : Boxee random video stretching/zooming...

I am having a highly irritating issue with the boxee box that I have unable been able to find a solution for myself, thus I turn to the boxee box forum for assistance.

I am having some strange video zooming/stretching issues when playing back just about every movie I have (typically 720p x264 MKVs). When the movie first starts playing everything looks fine and well, however after about 1 minute of playback the video stretches vertically all by itself about 25% or so and looks absolutely horrible. In fact the boxee menus all stretch and are often not visible anymore. On most occasions when I quit playback and return to the boxee screens the UI is still stretched but then after a second or two it correctly resizes itself (but not always), on other occasions I have been presented with a black screen and have to hard reset the boxee box.

I have tried factory resetting my boxee box and doing all the setup again, meticulously setting the overscan options, different TV resolutions etc, but still I get the same issues.

Is anybody else getting the same problems? Anybody have a solution?

Thanks in advance.

interesting thing here is that the UI is stretched when you hop back to it.

what are your video settings like ? 1080p, overscan 0, etc ?

I'm having the same problem.

My TV aspect ratio is set to auto and after a minute of playback through the boxee box the screen adjusts (stretching vertically) so that everything looks silly.

It didn't do this on the boxee on my appleTV so I'm presuming there is some difference with the signal from the boxee box that is confusing the TV?

It's really annoying and there is no way to get around it (if I adjust the TV aspect ratio to 16:9 the picture goes to the correct proportions but there are black bars on all four sides of the image.

Any suggestions / fixes would be most welcome.

Thanks,
Scott.

try this. go into boxee, settings, general, display. pick the right resolution. go into screen format & overscan. set overscan to 0 and aspect ratio into whatever is appropriate for your display (almost certainly 16x9).
now cycling through the display modes on your tv until the image stretches edge to edge. assuming you have our resolution matching your TVs native resolution, you should be able to do this without overscan.

now try playing back and see if you still get the same resolution adjustment issue

Funnily enough after I posted earlier I decided to give resetting the boxee box one more go. I did that, and then for no real reason other than just going on a hunch I decided to factory reset my TV (High end Panasonic Plasma) as well.

Well as you've probably guessed this seemed to do the trick. I now just have my resolution set to 1080p 24 and don't need to do any custom overscan setup or anything with boxee. The best part is that the vertical stretching/zooming issues have also gone, so potentially one of TV's settings was off?

Like the previous poster I have never had an issue before though (I own an Xtreamer as well) so I am not exactly sure what was going on between boxee and my TV, but hopefully this info will help any other users having the same issue.

Thanks for the tip. Unfortunately I can't set the overscan to zero because I need to make display adjustments to boxee which change the overscan and aspect ration buttons to 'custom'.

However, I've changed boxee from 1080p 50Hz to 1080p. I'm not sure what the difference is but it seems to have done the trick. The TV now seems happy with the small black bars at the top and bottom of the screen.

Thanks again,
Scott.

I have the same issue, happened just after I watched a movie in navi-x, exit out and had to change resolution to 480p to get a full screen...was hard to do with stretched video but i figure it out. then went back to 720p, got the stretch screen, cycled through my various formats on the tv and it came back. Seems either boxee or navi-x changes the tv format. which it should not

Hi there,

I'm also noticing the same behaviour. I've tried playing around with the various settings on both my TV (Panasonic 32LDX270) and the Boxee Box. Nothing seems to work...

If anyone has any further suggestions then that'd be most cool.

Thanks,

Matt

Tried every option. But cant seem to get the aspectratio right by it self.
Got a 1 year old Panasonic plasma TX-p42g10e.

I, too, am having this issue.

One interesting thing I've noticed about this problem (at least for me) is that the video always stretches at *specific frames* in certain videos.

The frames are always quite complex. They're usually very bright or have large patterns. In some case this can even be caused by loud or rapidly changing audio. I can even recreate this by jumping to the exact frame which is causing the issue.

Going on the above, my first thought was that it must be a problem with the video itself but streaming the exact same video files to a PS3, a Mac Mini or Boxee running on an HTPC shows no issues.

Changing resolution settings, inputs or even trying a different TV doesn't help.

It's almost as if the box is "underpowered" somehow and tries compensate by blowing up the picture.*

* Yep. Totally made that up. As you can see A/V stuff isn't my strongest superpower.

I too was having this problem where the image would suddenly stretch vertically on my Panasonic TH-P42PZ80 (3 years old).

I solved the problem after reading this thread by setting the aspect ratio to 16:9 instead of Auto. This had the nice side effect of making the image fit perfectly into the screen as before this I had to use 3% overscan to see the full UI.
