Sometimes basic knowledge is desireable to frame a
question of interest to those who may answer...;-)
PAL is PAL; NTSC is NTSC; in Mini-DV both are simple
digital data streams to the recording section of the
camera (and tape) and to the computer, but the analogue
interpretation for these is quite different, requiring
conversion. For best results, keep these different
TV-formats separate. If you have not, you would need
to work in NTSC-format with the NTSC material, then
convert the resulting footage to PAL-format, not a
neat process...
