have checked that only media centre 25 is running.
WinTV is running (not using any resources), but that is the case when MC24 is installed
Pc has been restarted many times.
Strangely enough it did work OK once yesterday after I responded No to the banner requesting software changes to be made to the Pc , that occurs when you select watching a TV channel, just wanted to see what files were being created. Following this I subsequently responded yes and all worked OK ( banner occurs twice, once for each file).
Have tried again today, and back to square 1 have swopped between 24 and 25 about 10 times and each time i get a frozen screen displaying the selected TV channel and have to end MC25 using the task manager as it is completely unresponsive
