Moving this discussion to here.
I also had some numbering issues when I did a re-scan of the SBS signal. World Movies showed up as a new channel (rather than just a re-naming of the existing Viceland SD) but because Viceland was already on LCN 32 the receiver ended up putting SBS World Movies at the end of the receiver’s channel list at 400. I had to manually switch it to 32. That happened on a fairly new receiver that usually handles these things very well.
By contrast when 95 changed from the blank screen SD to the HD version of 9Gem it didn’t show up as a new channel and just tuned in automatically.
On all the tuners I tried LCN 32 showed up as a black screen after the change to HD. Only a retune would get World Movies close to working.
