I think "-p /dev/dsp" is your problem on newer kernels. /dev/dsp is an OSS device. OSS is obsolete, replaced by ALSA. Perhaps if you find the name of the ALSA device it will work, IF transcode supports ALSA devices.

You could also try configuring the tuner in mythtv and then letting it do the recording for you using a manual rule.
