Query: not so usb

software installation on winxp sp2 locks the usb box to a specific port, and you can't change it to any other port. If you do, it'll ask you to re-install the driver again, and reinstallation will just fail. It's also not happy with my on-board realtek audio device, you still get the sound, but you wouldn't be able to control sound volume from winDVR. In general, I don't think the software is properly tested with the box, totally ruined my first impression with sabrent. They'll need to send me a good product for free in order for me to buy their product again.!!
