I was going to bin my LG DRT389H DVD recorder, because the disc drive had been failing to work properly for some weeks, and repeated attempts to use discs resulted in the tv picture breaking up and finally freezing, and locking out the remote control.
My partner said, "Could it be something to do with the Digital Switchover"."Very unlikely", I said. How could it affect the playing of DVDs?

I had followed the official advice at switchover date. I accepted the machine was dying, but I liked it, so bought an identical replacement. Amazed, to find the new machine showing the same faults as the "broken" one.

Nothing in the official publicity indicated that Switchover could cause anything like this. Two days of layman's googling found web sites like this one (the most informative) and the notion of signal overload, which I had never heard of. The LG's signal indicator showed that MUX channel 24 was far stronger than the other five MUXs. I re-scanned the channels, leaving out MUX 24, and the LG recorder worked normally again. I am in the Rowridge transmitter area.

If I reduce the aerial signal to make MUX24 usable, the other five MUXs collapse. It now seems that in a few days all of the MUXs are to be transmitted at equal power, and I can reduce the signal level of all equally.

If the official Switchover publicity had warned the lay public to look out for all kinds of odd malfunctions, I would not now be the owner of two identical, functional recorders. Luckily, I was not passing the skip recently, or I might now be the owner of only one.
