aspect ratio DVD still wrong

[Gravityz]

this has been a bug for a long time

when the a110 came out it displayed 4:3 dvd's full screen on a 16:9 screen.

after 2 firmware updates they decided to add black bars justr to make sure your tv(and al it's inteligence) could no longer display it full screen so it was forced to display on 4:3.

i know they did this to keep the corect aspect ratio(round will display round)

what they however forgot to check is how most dvd's are put together.

most dvd's have vob's which are 720x576(16:9)
if you however display this on a 4:3 screen it will be all wrong.

therefor they put 4:3 info into the .IFO files.

result 16:9 film on 4:3 screen will be displayed as 4:3(maybee with letterbox)

16:9 film displayed on 16:9 will be full screen like it should.

by forcing the black bars on te side syabas screwed over al known standards.

result some 16:9 dvd's(mostly kid dvd's like dora, diego etc) will display in 4:3 which will give the WRONG aspect ratio because the VOB is in 16:9

is there any chance that Syabas will correct this.

only solution at the moment is to use a program called IFOAR2WS which modifies all ifo files to 16:9
The main menu however is untouched so if you want this changed also you need to use DVDREMAKEPRO, correct the menu and only write back the changes to save time(CTRL+M)

first i changed al my dvd's to video_ts format because they refused to play in ISO.
after a couple of firmware updates the reversed everything so i had to change to iso format.
now with the 4:3 thing i need to edit every single ISO which is a pain(mount iso, correct files, copy everything to HD, makle new iso, copy back to A110)

would it not be simple to keep the standards like they are.

do not change the output of the A110. make the output of the A110 the same as if i would play back a DVD through my DVD player.

i know, i also changed a couple of dvd's to MKV which corrects everything at once but i like some dvd menu's.

I have no problems with any of my 16x9 or 4x3 films.

16x9 show up with the correct black parts at the top and bottom, while 4x3 show up with the bars on the sides.

This is how it should work.

What are your video connections and settings?

[Gravityz]

so you mean to tell me that 16:9 shows up with black bars on top and bottom and you are happy with it?

16:9 should display full screen on a 16:9 tv

offcourse you have 2 different aspect ratio's with 16:9

i think you have 1.85:1 which is mostly used in europe
you have 2.35:1 which is used in the usa

either way you can get rid of the black bars on top and bottom by zooming/cropping etc.

if you want to do a test

put a 16:9 dvd in a dvdplayer and see how it displayes
do the same with a 4:3 dvd

now do the same on the A110 and you will be seeing a difference.

in the beginning the A110 was working perfectly for 4:3 DVD's but people with 16:9 dvd's and 16:9 screens still noticed black bars.

in the newer firmware releases they changed this in favour of the 16:9 dvd with the 16:9 screen.

so 16:9 dvd's should display full screen.
4:3 dvd's should display 4:3

the problem is that the A110 does not read the format of the VOB file but it reads the ifo file.

so if you have a 16:9 dvd with the ifo says 4:3(to make it compatible with older tv sets) it will display incorrectly.

you can find al this info when you read a dvd with dvdremake pro.
it display's the vob format and the ifo format.

I apologize that I did not see the section this was posted in, but I have a c-200.

I dont need to make IFO files, or do any tests to show my point though.

I am in the US, and widescreen content shows up with black bars at the top, just as its supposed to. I do not have or desire and anamorphic widescreen setup, and am okay with how this works.

I am unsure if the c-200 and a-110 operate the same, but I assume they are very similar. I have no problems with mine showing widescreen and fullscreen content correctly.

[Gravityz]

ok no problem.

i think you have black bars because usa uses NTSC which has a different aspect ration than europe and the rest of the world.

thanks for the input

a C200 is indeed similar but a lot faster with hd content.

Most movies today are filmed with aspect ratios of 1.85:1 or 2.35:1
These ratios have been used for a very long time and aren't going to change any time soon.

Both ratios are wider than 16:9 (1.78:1).
Movies shot in 2.35:1 will always show bars and will only fill about 3/4 of the height of the 16:9 screen.

A 1.85:1 movie only fills the screen of most 16:9 TVs because of the over scan that is built into the TV. Without the over scan, 1.85:1 movies will also display black bars, albeit very narrow ones.

There are black bars in the movie theatres as well have a look next time, (In my local the screen changes shape which is cool but I do like the sound of PWM driven motors)

People are often get confused and think that the 16:9 aspect ratio was chosen for TV to match that of movies. this is not true it was chosen for technical reasons related to TV broadcasting and data compression requirements

16:9 (1.77:1) was reportedly chosen as it is the geometric mean of 2.35:1 Panvision Cinemascope and 4:3 NTSC. link
