To be honest... I don't know what this means. Apparently it was able to lock some channels, but what they are, if they are encrypted, I have no idea. Since MythTV isn't seeing them, I don't know how to tell another program to tune the card to one of those channels and copy it to a file so I can try to view the output in something like Mplayer. I'll keep tinkering though.... Thanks. > I'm not sure if this is an issue with the driver, or I'm just not > getting something right.
