The quality of video on a computer monitor should not be used to gage the quality of a DV stream. Only a monitor or TV can show you the reality of the digitized video. However, you must be able to put the DV stream up on such a monitor or TV. ("Monitor" refers to a professional monitor, like the Sony PVM-14M4U, and "TV" refers to a standard television.) Sony 8mm and Hi 8mm video can be encoded perfectly to DV using the Sony Video Walkman GV-D800, which has the benefit of a Time Base Corrector, or "TBS" (in short, both Hi 8 and Regular 8 video are tremendously improved through a time base corrector, which corrects for many of the common analog problems, turning what may appear as unacceptable video when played back through other means to acceptable video for editing.) The Sony GV-D800 plays back (with TBC) Regular 8mm and Hi 8mm video, as well as Digital 8, records as well, and provides a DV stream I/O through 1394 Firewire to and from your firewire Mac, plus provides throughput to a monitor or TV. Of interest, the GV-D800 is a video walkman, meaning it does have an LCD monitor built in, which can be handy for a rough cut in the field with a PowerBook. We have this unit for the oddball 8mm tape which do show up from time to time, and have brought it to distant field edits, as described, and regarding the 8mm performance, it is very acceptable to excellent, and replaces the need to suffer the pragmatic cost of a higher end 8mm deck. It is in the $800 range. Richard Brown
