Video format is 1920x1080, mpeg4 16:9, plays in VLC player on the PC with black bars top/bottom with no issues
Before the update it also played on the humax without stretching vertically
One thing I have noticed that when I click to play the media on the Humax, if I quickly press pause once the screen displays, it holds the correct format with the black bars present, once I unpause it just stretches up, I know its in the Humax box that the issue is, as it plays fine while connected directly to the USB/HDD port of my Sammy tv.
I only run it through the Humax as the HDMI is sent through my AV receiver for the surround sound etc that also works great with media.
Still trying to sort this issue, but it looks like I will have to revert back to the last firmware version.
cheers
*update
Just changed firmware back to version 2.02.46 and I have no stretching issue with the same media.
Can you post the full data requested in post 2. So far have not found an issue, you could PM me a link to a file with the issue. Without further info and unable to repeat the issue there is not a lot more that can be done. My box is routed to TV using HDMI via a Yamaha Aventage AV receiver.
It seems possibly down to an issue with the box not correctly identifying the correct pixel aspect ratio embedded in the file, but that is just a guess.
Hi, I will install the software tomorrow and post the info, thanks, but it was stretching every file that was in the letterbox format
I will post the data for a files that display correctly for me.
Trouble is the 1080P label is often used to describe content that is not actually 1080p.
The aspect ratio of a picture is defined by two parameters.
The Horizontal and Vertical Pixel count.
The data defining the shape the pixels should be displayed on the display. This is known as the pixel aspect ratio (PAR). A full 1920 x 1080 16:9 has a 1:1 PAR (the pixel data is transmitted as providing square pixels). A full HD display has 1920 x 1080 square pixels (actually comprising 3 rectangular sub pixels of Red, Green and Blue). In this case you have 1:1 data to screen pixel correlation. A HD Ready screen with normally 768 lines has to use the implied PAR to recode the content to produce a undistorted 16:9 image.
All HD transmissions used to be 1440 x 1080 (A non square PAR), to display these on a square pixel Full-HD display also of course needs recoding in the display software.
Then you can add any video distorting settings in the source and display, it's not surprising that problems arise. Even when you have the basic idea of the maths involved it can be blindingly confusing.
Random so called 1080p24 that works perfectly on my box in respect of video aspect ratio.
