PC to 1394 direct to disk--Got problems

We recently upgraded to the HVX200 from a DVX100B for chromakeying purposes. We're in a studio environment recording direct to disk using DV Rack HD. No P2 cards, no tapes.

Using XP and connecting with a short 1394 cable the computer sees the camera, but can't seem to get a video signal. Another computer has the same problem. Both these systems worked with the DVX100. No software on the computers (and we have a variety) can seem to get a video signal.

This is probably something stupidly simple in the camera configuration or operation, but I can't seem to figure it out.

We are not using the native modes.

Any ideas? (I'm hoping the answer isn't that a P2 card is required even though it's not being recorded to.)

You don't need a p2 card in the slot to capture HD. From memory you just have to set the hvx to 1394 HOST. Also, in the case you're using Edius Broadcast to capture, 720p isn't supported yet (1080's fine).

IEEE HOST mode is for offloading P2 cards to a SBP2-compliant Firewire drive.

In order to record to an NLE or DV Rack, set the camera to IEEE 1394 and make sure you use a non-native recording mode. Also, if this is the trial version of DV Rack 2.0, be aware that the trial does not support HDV or DVCProHD due to licensing issues -- it states so on the download page for the trial.
 
I've tried both 4 to 6 pin 1394 and 4 to 4 cables, I have a fully licensed copy of DV Rack 2 HD. Hmmm...wait a minute

...20 mins pass...

Bingo!

I don't know exactly what I did, but it's working! I did the following:

1) reset the camera
2) put the P2/tape switch in the tape position
3) turned on/off the camera
4) changed recording mode to 480i/24p (was 1080i/24p)
5) unpluged 1394 and replugged it in
6) looked under My Computer on XP and saw Panasonic camera
7) opened it up and saw live feed
8) Went into DV rack, selected to panasonic device and saw feed!
9) went into camera menus to change recording mode to 1080--not available in tape mode
10) flicked tape/p2 switch to p2 (oops! Should of turned camera off first))
11) turned off and then on camera
12) changed recording settings to 1080i/24p
13) no image comes up under my computer/panasonic anymore (I'm assuming this is because of the DVC PRO encryption)
14) unplug/plug in 1394 cable (to make sure that the connect died/restarted)
15) Live feed!

I don't know what exactly happened but it's up and working. I thank you all for your help.

I documented my step just so if someone else gets into the same strange problem it might help them.
