DVD player/TV crops my DVD-R

[James A. Murray]

I just made my first DVD-R with iDVD.  I am using a TiBook running OS 
10.2.1, and iDVD 3.  The disk came out fine, and on the first try, 
burning to an Imation DVD-R (10 for $15 at OfficeDepot).

But I am having a couple of problems playing it on my Toshiba SD-3755 player.

1. It crops the image so much that it truncates the titles that I 
added in the lower left corner of the iMovie.  [I did not have QT 
margins clicked in iMovie 3, but this movie was originally edited in 
iMovie 1, and has been moved to iMovie 2, and now to iMovie 3].

2. The player chokes at the same place in the credits each time, and 
shuts the player off!

I have tried the disk on a different model Toshiba DVD player, and it 
does not choke at the credits.  The cropping is still present, but to 
a lesser extent, on the different model.

Any suggestions would be appreciated.  I have re-rendered the movie, 
but won't burn it again until I get some idea what went wrong the 
first time.

thanks
