The "Coronation" recording stars okay (see tuned data) but the overlapping "East" recording doesn't tune. I see you have two dual tuners (dvb-s, dvb-c/t) but I only see references in the logs to frontend #0. Not sure if this is normal for these cards or not? Does your config show two dvb-s and two dvbc/t tuners?
Maybe similar issue here:
