When using the Channel = "Any" option under Auto / Standard Rules scheduling, when a programme is on a channel that has both SD and HD available then RS schedules both, hence hogging both tuners for just a single programme. To avoid this, could the "Any" option be replaced by two others: "SD preferred" which would record only the SD channel whether or not an HD channel is available, and "HD preferred" which would record only the HD channel when available but the SD channel otherwise.
