1 West is 0.8W on the PLI image .
Did you download some channel listings for it ,if so they are most likely setup for 1W and PLI wont recognise it.
I had the same issue on my 500s,I had to modify my channel settings to sort the issue.
Just upload this file to you \var\etc directory on your box, it is the latest satellites.xml from Reinh@rd. This will rule out the channel listings being the problem so if its still not picking 1west we can move on to something else.
I did a manual scan .
I then removed the 1w listings and redid my bouquets with the newly scanned 0.8w using Dreamboxedit.
Bit time consuming but it works perfectly
