When i Burn an DVD to an DVD-R it does not always play by itself when insert it into a dvd player, does not matter what player.
(they all support DVD-R)

I sometimes have to press play or the menu button.
and sometimes it does not work at all.
but most times it works.

what could be the problem???
What am I doing wrong?
I shrink the dvd9 with dvd shrink and burn it with nero6.
I use UDF1.02.
Burn speed is 4x

My burner is a Sony U10A 4x

Many Thx in adv.
Jerrel.
