Why Make MKV find two similar tracks?

[ponzo79]

Hello and sorry for my english
I'm a new user in this forum
I want convert to a blu ray disc (lord of the rings fellowship of the ring extended edition part 2) but Make MKV find two similar tracks....
Why Make MKV find two similar tracks?
which one to use?

I'm also a newbie with MMkv but the key here is to pay attention.

Pop the disc in a standalone player en verify the exact length and number of chapters, then compare with those with tracks in MMkv.

It will be evident which is the correct one.

There can be dozens of "similar" tracks on some titles. Sometimes, these contain versions that vary only in some signs or other text in the background that are different for different languages. Sometimes, many will have scrambled scene lists, in an attempt to confuse users as to which one is real.

toshibauser's suggestion is the first step - checking times vs. what the BD's menu says is the "right" track.

Thank your answer, but my tracks are very very similar....I'm a newbie but I am not stupid...I use MakeMKV from two years

The chapters are equal (21)
Languages and subtitles are equal
Size file .iso 36,33 GB
I converter all tracks and this is result:

File name track 1: 00001.MPLS
Size track 1: 29,36 GB
Length track 1: 2:02:34 (hs)

File name track 2: 01689.MPLS
Size track 2: 29,36 GB
Length track 2: 2:02:37 (hs)

I deleted all languages and subtitles except italian.
The length difference is because the track two start 3 seconds after
I checked both tracks but I do not find differences

Sorry for my english...

One iDea suggested by setarip_old was to just back the disc up, and then try the segments from the segment map and see what's what.

Or maybe check the BDInfo DB and see if that disc has been listed and read the report on it.

Both tracks contain segment 10 which is the main part of part 2 of the movie.

The second track contains segment 24 which is an additional 3 seconds at the beginning of that track.

I don't remember, but it may be black video to bridge between part one and part two.

You can rip both and play them and see what's at the beginning of the 2nd track (first 3 seconds), or do what Smithcraft suggests and back it up and play segment 24.

Thank you for your answers
But, i don't understand what you mean...
I checked the first second, and are black.
The video start three seconds later in the second track
Explain me please

Either track will give you part 2 of the main movie.

The second track includes 3 seconds of blank video.

The second track includes 3 seconds of blank video.

For you it's only this the difference?

Thank you very much

Don't forget also that (typically) there are at least 2 versions on many discs, such as "director's cut", "theatrical version", "extended version" etc etc.
