I recollect someone else reporting this problem, but I cannot now find the relevant post. In this thread I want describe the symptoms of the problem, and what (for me) is a usable work-around.
The problem manifests itself as the UP and DOWN buttons on the remote control or keyboard causing programmes listed in "Upcoming Episodes" to be unintentionally scheduled to record. Selecting a future programme in the EPG displays on the "Upcoming Episodes" panel all occurrences of that programme found in the EPG. Pressing the DOWN button on the remote control or keyboard causes the programme that had the focus to be scheduled to record. Pressing the UP button followed by OK in order to cancel the booking causes the programme to be cancelled, and then 2-3 seconds later it is scheduled again.
For many years I have used an HDMI cable to carry video and audio to the TV. But my old Nvidia card has (I think) a bug in its driver, whereby sometimes on wake from hibernation or restart of the system, video in MP plays but without audio. The fix for this is to exit MP, start the Nvidia Control Panel, disable audio over HDMI and click "Apply", then re-enable audio over HDMI and click "Apply". MP then works correctly.
In trying to eliminate the above sound problem, I decided to route digital audio from the HTPC to a separate DAC (contained in a Cambridge Audio CXN), and from there analogue audio to the amplifier. My HTPC is one of those that exhibits the so-called "silent stream bug". This causes the first few milliseconds of discrete sounds to be lost, and makes MP skin sound effects unusable. But I wondered whether using a different DAC (not the one in the TV) would solve this, so I enabled skin sound effects in "MP Config". Bizarrely, it is this that causes the unintended programme scheduling on "Upcoming Episodes".
So, the solution to the unintended scheduling is to disable skin sound effects.
If this were a common problem, I am sure that there would be numerous reports on this web site. So there must be some other conditions that are necessary in order for the problem to manifest itself. My guess is that it is using separate digital audio that makes this problem possible. I suspect that the vast majority of users these days use digital audio over HDMI (and so won't encounter this problem).
Why using separate digital audio should cause unintended scheduling of programmes on "Upcomng Episodes" when skin sound effects are enabled is perplexing to say the least -- it just seems too improbable to be true, and yet it is repeatable on my system.
