As we discussed in the speculation thread, you have the Thompson tuner in your DTVPal, which seems to work well in your near-Orlando-airport scenario. The Microtune tuner in the DTVPal Plus and DTVPal DVR is optimized for fringe reception. The main differences would tend to be that the Microtune is optimized for sensitivity while the Thompson is likely optimized for handling changing multipath distortion. I suspect that the Microtune tuner has slower time constants than the Thompson, making it less able to handle changes in the antenna that may occur.
One final possibility is that Dish did not do an adequate job of amplifying the signal in the DTVPal DVR before splitting the signal for the dual tuners, meaning that the signal is getting reduced too much for some locations that do not have a preamplifier. I doubt this is the case, but we'll have to see what the design looks like after someone de-lids this thing and reverse engineers the tuner.
I hope you can improve your reception, but as you say, this is a different beast...
