Topfield 5800/Troubleshooting/Recording Interruption
The Toppy only has two tuners, so it is sometimes necessary to alter one of the tuners in order to start a second recording. This will interrupt viewing with a "CYR" prompt, giving the user a choice to cancel the recording instead.
However, there is a bug in the system which means that the CYR prompt happens at unnecessary times. The [Xw] WatchNoCYR firmware patch fixes this problem.
