To capture video form a firewire device use:

dvgrab -frames 0 -size 0 -format raw -noavc -showstatus -csize 1000 tape
dvgrab -frames 0 -size 0 -format dv2 -noavc -showstatus -csize 1000 tape
dvgrab -size 0 -format

best options:

dvgrab -autosplit -frames 0 -size 0 -format raw -noavc -showstatus -timestamp tape

where

-frames number max number of frames per split
0 = unlimited [default 0]
-size number max file size, 0 = unlimited [default 1000]
-csize number split file when collections of files are about to exceed
number MiB, 0 = unlimited [default 0]
-format type save as one of the following file types [default raw]
raw raw DV file with a .dv extension
dif raw DV file with a .dif extension
dv1 'Type 1' DV AVI file
dv2, avi 'Type 2' DV AVI file
qt, mov QuickTime DV movie
mpeg2, hdv MPEG-2 transport stream (HDV)
jpeg, jpg sequence of JPEG files (DV only)
-noavc disable use of AV/C VTR control
-srt generate .srt subtitle files containing the recording date and time in SRT format.
-t, -timestamp Put information on date and time of recording into file name.
-a, -autosplit[=num] Try to detect whenever a new recording starts, and store it into a separate file. This can be combined with the -frames and -size options, and a split occurs whenever a specified event arises. Autosplit is off by default.
-ilme Force interlacing support in encoder (MPEG-2 and MPEG-4 only). Use this option if your input file is interlaced and you want to keep the interlaced format for minimum losses. The alternative is to deinterlace the input stream with -deinterlace, but deinterlacing introduces losses.

tape is the filename
