The various areas that are used now are just a makeshift solution for the low memory that was available on the FF DVB cards. I would expect a "modern" hardware to have enough memory to handle a full screen, 32 bit OSD. > -Extend the osd api for scroll commands Ok, that sounds like a good thing to do. VDR would still draw into its local OSD memory and do the scrolling there, but would not need to actually send the entire scrolled area over to the hardware and instead tell the hardware to perform exacly the same scrolling in its copy of the OSD memory.
