Even that probably nobody here has used this new recorder before, I wish
to get viewpoints and suggestions as feedback before I possibly go for
this solution myself. Maybe I oversee something?

First my selection from the manual:

/Datavideo Technologies //DN-300 can record HDV via the IEEE-1394
(iLink, FireWire) output from HDV Camcorders (.m2t), or DV from DV or
Analogue video sources (.dv).
The DN-300 can be as an external firewire drive from which files can be
dragged and dropped to a PC or MAC. The DN300 also has a built in
utility to convert .dv files to .avi files.

Records DV from Digital or Analogue Video Inputs (DV via IEEE-1394
(iLink FireWire) or Component (YPbPr) / S-Video (Y/C) / Composite (CVBS)
analogue video inputs).
Records HDV (.m2t) from HDV input (HDV via IEEE-1394 (iLink, FireWire)).
Full VTR playback functionality, including loop playback.
RS-422 control
GPI input
Drag and Drop file transfer to PC or MAC via IEEE-1394.
The DN-300 cannot be operated as a DV Device from a PC -The AVC Command
set is not
supported.

//The DN-300 uses a FAT32 file structure, so large tracks are broken
down into 2 GB files which are sequentially named. For example if Track
02 is 1 hour in duration it will appear as follows (max 99 tracks):

dv02.dv    (2 GB) - dv02 is the file name for Track 02
dv02_01.dv (2 GB) - Each 2 GB section is given a sequential _xx numeric
extension
dv02_02.dv (2 GB)
dv02_03.dv (2 GB)
dv02_04.dv (2 GB)
dv02_05.dv (2 GB)
dv02_06.dv (77 MB) - The last file in the sequence is likely to be
smaller than 2GB.

Once transferred to a PC/MAC files can be dropped onto a timeline, in a
suitable NLE application, and they will playback seamlessly.

The DN-300 has a built in file conversion utility which can convert .dv
files to .avi files (type 1 or type 2). You can choose the format that
best suits your NLE platform.
N.B. The DN-300 requires sufficient HDD space to create the .avi file.
For example a One GB .dv file will require at least One GB of free space
on the DN-300 for the .avi file to be created. Tracks that have been
recorded in M2T (HDV) cannot be converted to .avi
The converted AVI file will not be displayed on the track list, but it
will be available to drag and drop to a PC. The conversion takes about
60% realtime, i.e. A 1 hour track will take around 36 minutes to convert.

---------------------

Datavideo Technologies DN-300 DV&HDV stand alone, portable hard disk
recorder looks to be an interesting and simple solution for both analog
(S-)video to DV conversion, and for simple capturing of DV and HDV
(M2T). Continuously directly recording for up to 18 hours on the large,
portable 250GB hard disk can be made tapeless.

Monitoring on a standard monitor while recording DV and HDV. Recorded
files can playback on a standard monitor or the camcorders viewfinder.
The drawback as far as I think, is its lack of a HDMI out port. Maybe
its YUV port can be connected to a (PC connection) D-Sub port on a HDTV
for playback viewing.

Especially and of real interest here as I see it, is the feature to set
DN-300 in "hard disk mode", mount it and use it as an external and
portable Firewire disk for a PC or laptop for further NLE,
postproduction, archieving (backup) and/or distribution purposes on i.e
DVD/BD media.

My questions:

1. Although (as usual) only PC and Mac are mentioned, is here something
that may prohibit DN-300 to be mounted and used as an external Firewire
disk on Unix as well?

2. Is here something that may probibit the files and formats to be used
with Cinelerra as NLE?

3. At first I was somewhat doubtful about the FAT32 file system on the
DN-300 disk that did split larger tracks in filesizes of 2GB each. Maybe
this isn't any drawback, as 2GB in practice may be large enough to drag
and drop onto Cinelerra each time?
