Unable to burn completed movie with my photos and videos

I have windows vista home premium - after importing my photos and videos - I
completed my movie in windows movie maker - completed storyline and timeline.
I was told by forum to remove all transitions form storyline, I tried to
publish my movie again.....and the same error message pops up stating
Unspecified Error with no explanation - during encoding process about 17.6%
it stops - unable to create DVD. I was also told to check Event Viewer, then
windows log, then application log, which I did - information showed numorous
errors on the days I tried to burn - shows Error- level, Dates & times,
Source - User Profile, Event ID-1542, Task category-None. On the right panel
shows Actions - what type of Actions is needed is needed to fix this problem
- I was also told by forum to check Device Manager - and check if region is
correct - I did, Region 1 which is United Stated(Current Setting)- Please
Help...pulling hairs - want to complete my home movie. Do I need to Install
a program to complete my project. Windows Vista included service pak 1
