I contacted CCNow about my order for the PDA-ir extender and was told that Electric Dog's account has been suspended since none of the orders have been filled and there has been no contact since Aug 15th.

As an alternative I found the UltraMote extender:

Does anyone know if this will work with PDAWin's TV Remote Controller? It's a little more, but they may be a bit more reliable.

Yes it does work

This has been confirmed by a couple of folks over at AVS Forum. This is good news indeed.

I ordered my UltraMote Extender 3 days ago. As soon as it gets here I'll let ya'll know what my personal experience is with the extender.

The UltraMote Extender came in the mail today. Only took 5 days to get here. And I have to admit that I warily installed it into the CF slot. But my fears of the unknown were soon proven to be completely unfounded. The UltraMote for the Axim X5 works flawlessly! I reccommend anyone with an Axim to order yours today before word gets out and CardonWare runs short on supply.
