The burning in mode "DVD UDF" and the mode " VIDEO DVD "?

[guada 2]

Hello,

I have make a recording of 2 files of the same size (4.7 gb), UDF on one side and VIDEO of the other one.

By using my reader Divx H*B 3255, the DVD disk (VIDEO) plays very well.
When I put the other DVD ( UDF), the reading matches 15 min and stops completely.

My question:
The problem of reading of the mode UDF is it owed to the bitrate of this one?
Why a VIDEO DVD ( VOBS), has it more ease than a video DVD in the format UDF?
Exists it a technical detail which differentiates them?

Thank you in advance.

On a player Divx.

How reacts the bitrate with a VIDEO DVD (Video TS)?
How reacts the bitrate with a VIDEO DVD ( UDF)?

Which is the difference between these 2 methods (I speak only about the bitrate)?

Thank you in advance
