I just purchased Total Remote for my Audiovox Maestro because the author seems to take intrest in his product. During the last two months I bought Ultramote with the extender. While the extender worked great the software had alot to be desired. I also Tried PDAWin with the Ultramote extender but it didn't work. Next I bought one of the Laser ir-extenders and it didn't work with PDAWin either. After a couple of un-answered emails to PDAWin I gave up on them. So if anyone is interested in one of the extenders at a reduced price let me know. Here's hoping Total Remote will get the job done.
