Good Luck, Mike Mike, I've been using the stock Ubuntu 7.10 kernel (2.6.22.4) with just the Kworld ATSC-110 remote additions. I'll give that a try and get back if I continue to have problems. As for top quoting, sorry about that. Thank you, Nathan. --- Mike, I'm working on compiling the current v4l-dvb kernel modules (v4l-dvb-0c3e99a3f31c). Do you know if the Kworld ATSC-110 remote patch is merged into the code or do I need to run the patch, http://www.mythtv.org/wiki/index.php/User:Vprada#Kernel_Modification ? I couldn't find any mention of the remote code in the source, assuming that it needs patching still.

CityK, Thanks for your reply, but that is not what I'm seeing in MythTV and TVTime for /dev/video0. I'm getting signal from /dev/video0 when I use the upper input, not the lower one.
