if you captured via firewire DV then yes. With respect tot the data on the
tape it will be a 1:1 lossless transfer of data. The DV format itself is
5:1 compression but NO data is lost when transferring that thru firewire to
your hard disk.

hmm... tapes are cheap.

Are codecs involved during the transfer? The codec should be a
lossless one, right? Is it possible for me to find out what
codec is used by Premiere?

Codecs are virtually ALWAYS involved during any transfer.

The DV codecs in use are almost certainly "lossless" They
merely capture the DV bitstreeam and shove it into an AVI file,
unchanged. The original DV bitstream was already compressed
5:1 by the camcorder and no further compression is performed
unless you transcode into MPEG or something.

1) It likely depends on the OS you are running (and maybe the
hardware you are using?) There is probably a very common DV
codec that comes with the operating system (or with the Firewire
port if an old OS and an aftermarket Firewire port).

2) It doesn't really matter as it is almost certainly lossless and of
no further concern. (Unless you are doing something very unusual
you haven't mentioned.)

Uh.....,
1 DV tape = 1 hour of 5:1 compressed video info
(SP-mode, 60-minute tape).
3 DVDs = 1 hour of DV video-data (as above) or
3 hours of further-compressed playable-video (the
quality-loss is generally visible but acceptable at this
level of compression, but at double the playing time,
it is close to unacceptable unless the original image
has little fine detail and/or it has almost no image
motion...). And, the DV tape, if properly stored,
will likely remain playable over a longer period than
it would be with either of the other two storage methods...
