I am outputting an avi from Premiere Pro 1.0, 2 hrs 7 mins long. The output from Encore 1.0 shows 4.38 gig total size. On 2 players I have tested the DVD on, it plays just fine. The 3rd player (Toshiba TV/DVD combo) show fairly regular jitters/momentary freezes. The Toshiba has typically been the player that I have tested Encore output from and have not had any problems with the results. The DVD plays fine on computers.
