I'm a long-time user of MythTV, using DVB-T in the UK. My current Mythbox is running myth-master under Scientific Linux 7, a near-clone of RHEL7, an x86_64 distro. I know that long-lived distros like this are not a prime target for linux-media, but they have some attractions. I'm currently running a recent but not current stock kernel; it works for me. Later stock kernels don't see the Hauppauge pci DVB-T card and don't identify separately the two tuners in the Kworld usb device. I've also tried later kernels from elrepo, with similar lack of success. So, I do have a working box, but updating kernels is broken. I'd appreciate suggestions. I have posted earlier on the MythTV and SL lists, without getting suggestions leading to a solution. Thanks, John Pilkington ----------------- This one works: [john@HP_Box ~]$ uname -r 3.10.0-123.9.3.el7.x86_64 [john@HP_Box ~]$ dmesg | grep adapter [ 12.319211] DVB: registering new adapter (Kworld UB499-2T T09(IT9137)) [ 12.939916] usb 2-2: DVB: registering adapter 0 frontend 0 (Kworld UB499-2T T09(IT9137)_1)...
