what should i do if i have a completely edited movie file on Adobe Premier and i want to burn it to a CDR or DVDR. I'm just curious what quality and file type i should export timeline before i burn it. It's only like a two minute long clip and when i burn it as a quicktime movie, it's almost 3 GB.

For making a VCD or DVD, check dvdrhelp.com

If you want to burn just a movie onto the CD then you can burn quicktime/WMP/divX/AVI/etc. Don't burn an uncompressed movie onto there (i.e. you used no codec). Uncompressed is something like 65GB per hour. It won't play on most computers. I suggest exporting a microsoft DV AVI file (use all the presets).
