losin video quality when uploading.

[pafty]

My son and I are making a video compilation of some of my acting work. The clips come either from DVDs or recorded from TV and transferred to DVD. He is using imovie and on his computer the compilation looks good. The different clips have different qualities but all very acceptable. 2 problems. We would like to burn the video on to a dvd but find that idvd is not preloaded on new Macs (drat). is there a way around this? Also we would like to upload the video to Spotlight. my son did an experimental upload to Vimeo but that lost a lot of quality. Is there a way around that? Please explain in basic idiot proof terms. many thanks

Encode the videos into .flv and mp3 audio and try again.
