Just wanted to answer my own question in case anyone has DP-67 bluetooth issues in the future.
I hard reset and flashed the ROM of my iPaq and it's now up-to-date. I also installed the latest Leaf DP-67 app Yair sent me and I'm happy to report I shot for a solid 2 hours today with zero issues. I also kept the iPaq in the front pocket of my waist pack while shooting so I never was way out of range with the bluetooth connection.
Now if I could just find a battery solution that provides longer shooting life I'd be a happy camper.

Bob, I tried the larger batteries under the digital drive, but it doesn't fit in the U bracket and you have to be careful with connectivity. Also the weight gets up there with a 8x10 Linhof with those batteries and the drive.
Actually since the Valeo has such a small buffer for shooting non tethered, the ubracket the drive the batteries and the I=PAQ unit all require a lot of chargers and gizmos it's just as easy to tether using a 12" or 15" powerbook.

That way you have an almost unlmited buffer and the Valeo and leaf V-8 and stable and very fast.
I run a powerbook battery powered and it will run for 1/2 day on a single charge.
Given all of this I do see the value in some situations using the Dp-67 and an I-paq, which is one of the reasons I bought the Aptus-22, though it still isn't available for my back.
AFter 2 years I guess it won't be made available for the A-22, though the last version of the Dp67 for the Valeo was very stable.
