has anyone encountered this problem.

I join svcd's with mpg2vcd so i have one image (svcd) then i use DVD2AVI to sinc up the sound then i encode using TMPGEnc Plus to m2v and mp2 then i use TMPGEnc DVD Author to author and add chapters/menu's and then burn with Nero, lately ive had a few films that only play properly on certain dvd players, when i play the film on either of my dvd players its fine and plays perfect, but when i lend films to my brother hes datawrite player wont play smoothly, the picture freeze's and the audio continue's to play flawlessly, ive noticed that this only seems to happen with a couple of release groups, Tcs seems to cause the problem everytime, but centrophy releases always play perfect.

just as a sidenote, when i use DVD2AVI any ntsc film which is 29fps i convert to 24fps could this cause the problem.

thanks in advance
