Synopsis:
If a tvchannel is selected in the tvguide (left column), mediaportal shows detailed singleChannel-information. In special cases, mediaportal does not show the information of the channel i have selected before, but the information from another channel.

Reason: _singleChannelNumber-field in TVGuideBase is not refreshed correctly (it is only updated, if vertical navigation is done within the left "channel"-column).
Example:
- Open TVGuide and switchmode by selecting a channel in left column
- go back to tvguide
- navigate to the right side to went out from the channel-column
- navigate up or down, so that another row is "activated"
- navigate to the left until the channel-column is reached and press OK to enter singlechannel-mode
--> Mediaportal shows up again the channel-information of the channel, thats singlechannel-information was shown first

How to fix it?
In SwitchMode() of TVGuideBase add one line:

...
_backupChannelOffset = _channelOffset;

_singleChannelNumber = _cursorX + _channelOffset;
_programOffset = _cursorY = _cursorX = 0;
...
