No satellite position change from timer

DM7025 with PLi image. It is possible normally change and see channels from different satellites configured without problems. I use diseq 4 port switch and both tuners are connected in series with same settings.

I leave box on channel from first satellite a standby the box. On timer I have recording entry from second satellite position. Than box stay on firs satelite and record blank. It is timer problem only.
Satellite change take a time.....
