The reason I ask is because, and I haven't entirely ruled this
out to source ( mpg) files yet, but the DVD I burned last night,
contained one splash .jpg as sort of an intro , then had two
660MB mpg-1 files, that I myself did not create, but had downloaded.
The resulting DVD would skip in playback intermitently, often artifacting,
first before skipping then eventually getting to a point that the
artifacting was too much, and thus the DVD stopped and went back to menu.

So just as I'm troubleshooting this to keep in mind for later:
I know the "garbage in, garbage out" rule, but could Toast 6's encoders
screwed up the files that were in the DVD? I am burning now the MPGS
to VCD using VCD Builder 1.1 to test and see if it is the source media,
but just thought I'd throw out this to get any feedback/ideas...
