[mythtv-users] DV Recording via IEEE-1394 Firewire with MythTV

So the corner is nice this time of year.
Wallpaper peeling and paint chipping that kind of thing.

Okay so neither of you guys said go away in those words.  You just 
didn't answer my question and told me to use something else besides MythTV.
I personally felt that not answering my question and telling me that 
MythTV isn't the right tool is the same as being told to go away.  It 
was a question, still unanswered.

Can or does MythTV record DV via the newly supported IEEE-1394(firewire) 
port?  I know IEEE-1394 was added for cable boxes.  But in none of the 
posts did anyone say anything about that.  Or say "NO" it does not 
record DV.  Since the original intention of the IEEE-1394 port was DV 
footage transfer and it is the oldest use for this port I thought the 
question had some merit.  The IEEE-1394 port has expanded over time to 
be used for a ton of stuff including hi end cameras, hi end audio 
boards, even networking and now Cable boxes.

I understand that MythTV does not have IEEE-1394 protocols built in to 
turn the cam on or off or do anything else with the camcorders 
transport.  MythTV works thru scheduling.  And in this respect it is 
difficult to use for anything except recording TV.  I would still like 
to record 2 DV streams at the same time into a server.  If MythTV could 
record DV then it would be the quickest and easiest solution for me to 
do that.

So I guess a different question that may get a better response is, Does 
MythTV have a plug in to record video from Camcorders via DV?  Or an 
editing plug in?

I think one of the major things that MythTV is missing is editing(not 
just file truncation).
Again that is my opinion.  Obviously you guys don't share it.

I am not a programmer.  So that is why this is a question being asked on 
the users forum.  Not the dev forum.  I will go check out the linux 
packages that exist for editing and see if they have the ability to do 
what I need.  Also see if they could be a potential plug in for MythTV.

I would still appreciate an answer about recording DV footage via the 
IEEE-1394 port.
