Hello! I tested this patch series with: DD Cine S2 V6 DD Duoflex CI (single) DD Duoflex S2 V4 (stv0910/stv6111) VDR 2.3.8, ddci2 Plugin 1.5.0 The SAT cables were connected to the DD DuoFlex S2 V4 card and VDR was instructed to use this device only. I checked the signal values with VDR and dvb-fe-tool and both showed the same values than before (without the patches). I did a recording of ORF I (Austrian TV) and was also watching ZDF (German TV) simultaneously. All worked as expected! With this eMail I add my Tested-by: Jasmin Jessich <jasmin@xxxxxx> for this series. BR, Jasmin
