I use Preimer 6.5 and that has and Mpeg encoder built in which exports projects to DVD encoded files. I use TMPGEnc DVD Author to make menus before a Nero burn.
Hope this helps. 6.5 is free off web site, you just need the key!
Well Adobe Premier 6.5 retail comes with Sonic DVDit so you don"t need a Authoring Program if you have the retail version...also Premier Pro 7 is out, which is so far the Best version, It has an Good Quality Mpeg encoder and a AC3 encoder(TRIAL) and it is Much Faster than any other Premier Version accept that it only works on XP and with Intel proscessors or Newer Athlon XP Processors with SSE ..But I still Like the Functionallity of Useing Vegas Video 4 the best, it has better Transitions and effects and is easier to use But the Rendering speed isn"t as fast as Premier....Cheers
