Myth currently supports:
1) Blank frame
2) Scene change
3) Blank frame with scene change
4) Logo (the little channel identifier logo)
255) All (combines all the above--basically blank frame with scene 
change and logo)

So, my recommendation is to set it to use All and it should work on your 
channels with blank frames and/or logos, and will do better than just 
blank frame or logo on the ones without.  Set it in Settings.
