Thanks Mark, I missed that. I have a text file of ignore words from another system, so I poked around and I see that in X:\Storage\.HomeTheater\settings\TheaterConfig.xml this line <string name="scanFilterListString">trailer,yyy,zzz</string> shows whatever one enters manually because I entered yyy and zzz after the default trailer, so I assume I can simply dump my comma-delimited list in there after the default trailer. Ah yes, much easier! I see when I tried storage://Posters then I ended up with this less convenient path... X:\Storage\Posters\.HomeTheater\Posters So now I'm wondering how best to start over. I've got .HomeTheater folders all over the place (including on remote drives where I'm guessing I don't want them) from testing. To start totally over with a fresh Posterwall scan I'm guessing I select "Remove" from the menu for each of my Sources, then maybe delete all the .HomeTheater folders using my computer's file manager (including on the UHD3000 over Samba). Anything else to make a fresh start on a Posterwall scan? Yay, thank you!!
