Thank you Stanza.
I tried your suggestion and their was no change to the behaviour. The tuner is recognised in System information but again it is not working in the Video Station Application.
I am using a Dell Alienware X51 system to host the XPEnology with the only other running apps are antivirus and Surveillance station. Everything has been working great before I tried this.
The DS411J CPU runs in the 95+ percentages when recording tv so I figured I would move the recorded tv application over to the more powerful CPU. So far no luck
They are both running 4.3- 3810 although the DS411J also has update 1 after the DSM version.
I have just updated both systems to be update 3. The symptoms remain the same.
Hope this can offer more insight.
Thanks again Stanza
