using a DVDcamcoder you stumble into the following hurdles to go:
* DVDcamcorders don't support the firewire protocol
* slot-in drives can get damaged, inserting non-standard-shaped disks (does your camera use normal or miniDVDs?)
* your disks have to be finalized in your camera - read camera's manual how to accomplish that...
after that, you can handle these DVDs as normal ones (selfmade have no copyprotection, so no need of usage of any Ripper/Handbrake..)
you will realize a loss of quality, due to the nature of DVDs, which use a deivery-format, not meant for further processing, but we do read reports here, some people are still satisfied...
your options are, in recommended order:
*
DVDxDV (free trial, 25$)
*
Apple mpeg2 plugin (20$) +
Streamclip (free)
*
Cinematize >60$
*
Mpeg2Works >25$ + Apple plug-in
* Toast6/7 allows converting to dv/import dvd, hit apple-k
* connect a miniDV Camera with anlogue-in to DVD-player and copy to tape/use as converter
