I had a look into the Cin-GG manual chpt 13
"Capturing and Recording Media", but could
not see Firewire media transfer was
mentioned. However, in the Appendice
section B.2 Configuration Features, Optional
Packages is found:<br>
<blockquote>--with-firewire use
firewire (auto)<br>
--with-dv use dv (auto)<br>
</blockquote>
Does this mean that Firewire/dv capture
already is supported or optional can be
configured?<br>

I guess that's not just for me ;) but will try dvgrab
again (tested it once several years ago), when my
camcorder is back from service.<br>
The reason is my 10 years old FireWire based DV/HDV
recorder seemingly is dead.<br>

I looked up some of the older discussion about dvgrab on
CinCVS/Skolelinux mailing list and the referenced manual wiki:<br>

<p>There is no perfect solution so far. One possibility is to run
the test-mpeg2 command available with the sources of <strong>libiec61883</strong>.
Use this syntax:</p>
<div>
<pre><code>test-mpeg2 > hdv_tape.mpeg</code>
</pre>
</div>
<p>and press <strong>Play</strong> on the camcorder. You should
not run any heavy resources consuming task on your computer
since the lack of caching in test-mpeg2 causes frame drops.</p>
<p>New version of dvgrab seems to support HDV. Minimal example:<br>
Syntax:</p>
<div>
<pre><code>dvgrab -format mpeg2 myclip</code>
</pre>

) you might run into troubles trying to record exactly HDV
stream - because it is not DV video, but mpeg2. There is code
in DVB input module for dealing with this, but it probably
must be wired to DV /firewire module, or something like this
should be used in ffmpeg.C for pre-decoding compressed buffer:</div>
