[Cin] dvdcreate and filempeg patches

[Phyllis Smith]

Tested all patches with or without Deinterlace and with Format changed to
Bottom Field First.  Everything seemed to work and created DVD media and
played on player attached to TV.

Not sure about adding "-c" to the mpeg2enc but it did not cause any
problems.
Thanks, I will check in to GIT the next time I boot the desktop.
