Good. I had once wasted about 3 hours of debugging code when I first ran across the "oops I didn't push the cable in all the way" bug. :) > I was at the point of downloading the > v4l-apps, but I couldn't find something with the cx18-ctl util in it. > Were you referring to the I downloaded the dvd-apps tip.tar.bz2, from > http://linuxtv.org/hg/dvb-apps/, but no cx18-ctl, I searched > ivtvdrivers.org, but no reference.

They were recently moved out of the driver tree into their own git repository: http://git.linuxtv.org/v4l-utils.git http://git.linuxtv.org/v4l-utils.git?a=tree;f=utils/v4l2-ctl;h=9c40b0506a44a9640eda38bb48360d65f6f910f7;hb=HEAD > I'm also curious, now that I've got receive (which I wasn't worried > about), how do I get transmit? Unload ir-kbd-i2c, and use lirc_dev, lirc_zilog (or lirc_pvr150) and all of the lirc userspace tools.
