DVD-R not playing

[johneboy]

Hey guys,
Just burned Black Hawk Down.. And its not playing
When i stick it in my Apex 1200, it will show its a DVD, but never start playing...
I burned it using ISO/UDF (1.02) with Nero, which has worked in the past.
I first burned it onto a DVD-RW, as i always do to make sure it's gonna work.. It didnt play with my RW either, did the same thing.. but i have seen it do that in the past when i didnt fully erase before hand.. just quick erase.. Also i have used Memorex -R's @ 1x, and now im using TDK @2x..
Any ideas? Right now im current doing a Full Erase on my RW, so i can try again.. but anything i should check or do different?

ok, so i went into IfoEdit, and hit "Get VTS Sectors" and "Remove P-UPs"
Now its playing on my RW, however, it seems a bit Jerky when playing.. I have heard this could be an issue with progressive/interlace mixups..
anyway i can tell what my movie is? (black hawk down)
