I don't recall seeing this issue reported before, perhaps somebody will remind me. Warm start this evening (boot from standby) - silence! When I glanced up there was the installation dialogue on screen: language, screen ratio, etc, and no channels tuned. Thank AF for auto schedule backups! I don't seem to have lost any media files, the CF is intact, and I'm still on 1.02.27. A manual tune and a schedule restore later and I'm up and running, but could have been messy.
