I recently created an anamorphic DVD for presentation on a widescreen plasma TV. In the titling there is noticeable pixelation. I've exported my movie from final cut with no compression and used dvd studio with 2 pass VBR at approx 8.0 bitrate, and only once I burn it to dvd does the distortion become noticeable. Is this normal because it is stretching it out to widescreen? How do commercial film dvd's go widescreen without any pixelation?

Films on commercial dvd's are being downsampled, if you did not shoot with
a native 16:9 camera your footage is being upsampled which can cause
problems. However, I would think the problem may be in the screen, which
should be easy enough to check. Just watch the disc on some other screens.
