Comment 2 for bug 452779

I am seeing the same thing. Just upgraded to 9.10 Mythbuntu. Deleted all capture devices and started over. HDHomeRun scanned fine, the digital side of the Hauppauge 1600 also scanned fine, the analog side of the 1600 hangs at us-cable 16. In the terminal window I get:

I can click the "Stop Scan" button and that will end it, so at least the GUI is responsive.
