Testing on mga6 for x86_64, Mate desktop. Before the update there was a lot of CPU activity even before changing channels. Launched from a terminal it generated a continuous stream of debug messages and certainly after changing channels all eight cores were heavily used. Updated to version 2.0.13-1 and found that the channels needed to be retuned. Filtered out radio and tried a few SD and HD channels. Very few messages in the console and the total cpu usage remained less than 30%. Stopped kaffeine and tried $ kaffeine --lastchannel Came up in digital TV mode, tuned to the last channel selected. Restarted and selected 'play file'. Opened 'La Petite Voleuse' which played fine, sound and vision. Switched to a newsreel clip. Switched to HD television. All OK. Checked the programme guide - titles unreadable for many listings - an old problem. pavucontrol described the audio stream as VLC media player (?). Kaffeine audio slider working. Tried instant record - a minute or so then stopped it. Played that back OK in vlc but the clip appeared in the user's home directory as ''$'\001''¿®ŋ)¬X°x!9.m2t'. Reloaded kaffeine to play a Voices of Music video. OK. Seek slider worked. $ kaffeine Bach.m3u That succeeded in parsing the playlist but did not list it. Skipping tracks worked - OSD for each track for a couple of seconds. Pause and resume functioning. Switched to TV AlJazeera HD and paused and resumed that. The cpus were never overloaded in any of these operations. This is definitely OK.

Len could you share with us what hardware you are using to test this. Like: HAUPPAUGE COMPUTER WORKS 1191 HVR950Q HDTV TUNER USB ATSC TUNER https://www.amazon.com/HAUPPAUGE-COMPUTER-WORKS-1191-HVR950Q/dp/B007WM1QTI/ref=sr_1_6?s=electronics&ie=UTF8&qid=1506271953&sr=1-6&keywords=usb+digital+tv+tuner&refinements=p_89%3AHauppauge Or whatever is needed to get kaffeine to display digital TV stations on Mageia. Thanks

@wilcal Bill, this is a PCTV Nova USB stick from a few years back. The latest Nova stick has different hardware components which are not yet supported by Mageia - I have loaded what I think are the correct firmware files but no go. The em28xx driver probably needs to be brought into line. Posted a bug on that more than a year ago. IIRC the later version can deal with satellite and cable transmissions as well. Anyway, the older version works out of the box, connected to the TV aerial (antenna). It contains a Sony CXD2820R card. The strongest channels come in at SNR ~2500 db. From lsusb: Bus 003 Device 002: ID 2013:024f PCTV Systems nanoStick T2 290e Hope this helps, and sorry for the delay; VirginMedia decided to start upgrading their broadband and television networks at the critical moment - likely to take five hours.

It appears that the Hauppauge line is somewhat of a default standard in this market. You think Mageia/Kaffeine would work with one of those?
I've asked on the Forum if anyone has had any experience with one of these things: https://forums.mageia.org/en/viewtopic.php?f=8&t=12014
Yes I am sure my old WinTV Hauppage device worked with kaffeine in the past, dvb-t only though, no HD. I usually watch TV via vlc and it did work with that. There are four TV sockets in the house so I'll try kaffeine with the Hauppage on another machine.
Note all the natural disasters lately. What would be nice is to designate a USB ATSC tuner(s) that equally work with some app on Mageia ( Kaffeine/VLC) and also with an Android app ( PadTV ) on a Smartphone. Same device works on both platforms.

I tested with PCI hardware DVB-T tuner on x86_64, and confirmed that 100% CPU is not there anymore with this version. Unfortunately, I have no i586 install in this system.
Don't let me hold this up. If everyone here is comfortable with this push it on. I've budgeted a Hauppauge WinTV-HVR-955Q for next month and will tinker with that. If it goes well I'll post it in my thread in the Forum. If there's a problem I'll start a separate bug. I think the 955Q is probably the defacto standard.
