Hello, > Neither set_tv_freq nor set_radio_freq sanitize-check the values > against limits ! I would like to second that this is a significant problem: I always thought that my radio and/or my antenna were broken because I only got noise from `radio'. Now I retried `radio' with a configuration file (had none before) and everything works fine! So it is the tuning to frequency zero that is causing the problem (new Hauppauge Win/TV w/ radio). IMHO, this should be trapped in the kernel, and not in userspace. Regards, Wolfram.
