Scenarist warning

[arlsair]

Hi,
I created the script with ScenAid v0.9.0.25 and on compiling I get this warning:

Warning The Prev Cell<VTS6_Title1_PGC1_PG1_C1> and the Current Cell<VTS6_Title1_PGC1_PG2_C1> are connected seamlessly and the Current Cell<VTS6_Title1_PGC1_PG2_C1> has only one VOBU.(PGC:<VTS6_Title1_PGC1> (Title:<VTS6_Title1> VTS:<VTS_6>)
Warning Some DVD players have problems with this limitation.
I really don`t know, what they want to tell me. I searched for this warning without success.
Does someone understand this warning and can explain it to me ?

basically a small single vobu cell after a large cell could potentially not give a dvd player enough time to buffer the data causing a buffer underflow . this could result in non-seamless playback (maybe worse in rare occasions). most players are immune to this, thats why its just a warning and can be ignored.

Great explanation. Thanks.
