NO.
FCP does not like working with non editing codecs.
Rip those DVD’s to DV50 or Prores. You’ll have better quality.
When done, export using “current settings” and drop that file into compressor to create your dvd files.
Always maintain the highest quality throughout the process.
If you shoot HD, but your going to SD DVD, you wouldn’t lower the quality of the footage. If hard drive space is short, get some more.
