The Pioneer DVR-310 and DVR-510 have DV in/out capabilities. In the manual it states that content can be output to a camera as long "as there is no copy protection".
This is pretty good if you do PC editing as it will allow a higher quality picture than MPEG2 although 4 conversions will take place: MPEG video to DV out in recorder, DV input to MPEG2 conversion for pc editing, then MPEG2 conversion to DV out in the PC, then DV input to MPEG2 conversion in the Pioneer recorder. It seems that editing on the DVR-510 would be the most wise for maintaining quality but then again, loss may be very minimal to gain the customization of a DVD. 1 poster said Pinnacle software worked with the Pioneer Output but some other software wouldn't. I guess it would be worth the try, but be aware that most DVD authoring software burn DVDs with a HUGE LPCM 48Khz audio file that's about 1.3GB for a 2 hour DVD. That equates to filling the DVD with a 2 hour movie that's less than 4 mbps. That's pretty lossy quality caused by the huge LPCM audio file. Ulead Movie Factory ""3"" authors and burns using Dolby Digital 2.0 which only uses a ~400MB file for a 2 hour movie allowing that movie to fill a DVD with a bit rate of ~5mbps. That's pretty good quality and is the norm for stand alone recorders. Beware as Movie Factory 2 authors with LPCM, you need ''"3"".
Have a good one.
