freeze frames when encoding with Decklink card. HELP!

Wise men,
some how, freeze frames are being generated when I am encoding HD material via my Decklink card.
I am not sure what is causing it.

first off let me say I am pretty certain that it is not the camera doing this.
when played back on a HD monitor directly from the camera, it plays fine. no freezes, nothing!

Here is my set up.
G5 dual 2.0 G5 Jam 2.5 gig Ram

HD10U camera output- HD component into AJA HD10A into Decklink HD card into FCP 4.

when the clip is played it runs fine for 4-6 seconds then a freeze of 2-4 frames will occur.
the freezes will continue from that point on, about every 1-2 seconds. (1-2 frames)

I have tried different settings on the encode.
720p with the AJA at 60 & 59.94
1080 with the AJA at 60 & 59.94

I have also tried different Blackmagic codec on the FCP side.
perhaps assigning the proper TC. Drop or non. the clips currently have no TC

It seems like it could be a frame rate or hertz issue. like it needs to catch up or invent frames to keep things in line
.
3:2 pulldown issue perhaps. ( from where I don't know)

something is causing this and it's not the camera.

I am grasping at straws here!

Need some ideas!

some ideas

There was a post from a guy, with same setup. search previous threads and send him an email. I know there was talk of the aja box needing tweaking at factory to play well with the HD1. Can the aja be set to 30p ??
I use the aja box at my post house to go into their decks. I had to play with the aja box but it worked.
The blackmagic guys in melbourne australia where they make the decklink cards are amazing for support. call them... and the aja guys..
i'm getting the same setup but waiting for the new G5...

good luck

Freeze Frame Saga is over

Here is the final outcome.

Darren Kelly called it correctly.

the speed of my storage drives was causing the entire issue.

I had formatted my storage with Extended (journaled)
this slows you down 50%

Dont use Jopurnaled!

hd problems

a month ago i tested aja hd card with huge disk array, and the same problem occurs. the guys from the dealer spent tons of hours to resolve the problem. bot no luck. after a three weeks they decide to separate the video from audio and... voila! it worked! looks strange, but it worked.
but anyhow, i'm waiting for decklink. need to test it with same configuration...

p.s.

i just mentioned aja hd - i'm talking about the HD card itself, not the aja converter.

Why are you using an HD card to get the video off the JVC?
