It means I apologize for apparently misstating the facts originally.It now appears that the recording problems are only with the 2 QAM channels that have changed frequency, and only when another recording is already in progress. (I've only tested with the other recoding being analog) May indeed be that the changed frequencies are inducing interference. There look to be striking differences in signal level and quality for the troublesome QAM channels, depending on whether another recording is running or not, not that I know exactly what the numbers mean.I get 4 useful QAM channels, plus 2 others that are intermittent (and NOT tuned by any of my TVs), plus 2 or 3 others that I never look at.The 4 are named KVOAHD, KGUNHD, KMSBHD, and KOLDHD. The latter two changed frequency recently)Here is the test sequence that goes with the logs.1. stop MP and TV2. delete all logs3. start MP (and TV)4. use Scheduled -> New to start a recording on analog channel 3 5. use Scheduled -> New to start a recording on KVOAHD6. verify recording playback and normal MP operation -- both good7. stop recordings.8. repeat 4 - 7 except use KGUNHD  -- all good9. repeat 4 - 7 except use KMSBHD  -- recording is heavily pixelated, torn, distorted; audio intermittent and out of sync; MP operating v-e-r-y s-l-o-w10. stopped MP, TV missing per Task Manager, do not delete logs, restart MP11. repeat 4-7 except use KOLDHD -- recording is heavily pixelated, torn, distorted; audio intermittent and out of sync; MP operating v-e-r-y s-l-o-w, eventually 'Connection to TVserver lost'12. stopped MP, TV missing per Task Manager, do not delete logs, restart MP13. start recording on KMSBHD only -- all good14. stop recording15. start recording on KOLDHD only -- all good16. stop recording17. compress and send logsI think the channel frequency detail is in the logs, but I could also post the TVsetup page that shows that.I probably should have also tried scheduled recordings with zero pre and post record, and will do. If that doesn't work, I guess I'll just have to avoid the problem ---Major thanks for sticking so long. I probably deserve this one -<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite4" alt=":mad:" title="Mad    :mad:" loading="lazy" data-shortname=":mad:" /></blockquote>
