An analogue>DV converter would plug into the cam via composite or S-Video and audio analogue outputs and into the PC/Mac via firewire. Or you can get an internal version (for a PC at least, not sure about a Mac).
Don't bother with the old PC to CD route. The quality of the video on CD would be far too low to bother transfering to a DVD.
A standard DVD player can not record. You can however buy DVD recorders to do this, and some even have a firewire input, but that is no good for you

. You would connect the cam to the DVD recorder in the same way as to the converter above.
Mark.
