Using the camcorder to play back or edit tapes might save money, but it can shorten the life of the camera. If you plan to do a lot of editing, a professional deck with i.LINK, timecode and RS-422 serial control provides more accurate tape transport, better quality and faster shuttling.
A DVCAM VTR (or camcorder) can play back a tape recorded on DV and DVCAM. But, you can’t play back a tape recorded in DVCAM format on a DV camera or deck. High-end DVCAM VTRs also play back DVCPRO tapes.
