Nathan, Please do not top-quote.... As per your description above, you are correct... HOWEVER, now I understand your issue -- you are running old code. If you update to the latest v4l/dvb modules via linuxtv.org mercurial, you will find that functionality has been restored as per your desire. Please see http://linuxtv.org/repo ...for instructions to upgrade your v4l/dvb modules. 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. Thank you, Nathan. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
