Answer 1

My purpose for copying to a CD or DVD is so that I can make copies and send to friends and relatives. What is the best way to get these files on a CD/DVD with the right codecs?
The easiest thing to do is to simply tell your friends and relatives to copy the files to their local hard drive before playing them. Your basic problem is that data discs have a limited real time transfer rate. Since you say VLC plays the files fine, I might suspect its player is likely buffering the data while the QT 7 Player is not.
Data discs made for playback directly from the CD or DVD are normally encoded using MPEG-4/AVC (H.264) video with AAC audio. This is a modern codec which has specific settings to re-package the data (i.e., must be encoded using the multipass option and then select the "optimize for CD/DVD" option).
