[vdr] HD suisse;SRG SSR idee suisse (H.264 under xine)

Hello,

my country now as an HD channel : HD suisse;SRG SSR idee suisse:12399:hC34:S13.0E:27500:10180+180:0;131=deu,132=fra,133=ita,134=eng:0:0:990:318:8500:0

It's 720p with AC3 for the four audio. I have a quiete strong CPU but it's barely enough to decode this as vdr/xine seems to only take one core of it, even if I have set 2/4 for the processing.ffmpeg thread count.

(By the way, should I better set it to 2 as I have only two cores or to ??? )

Anyone know how to use both cores for this channel (like it's done for BBC HD;BSkyB:10847:vC56:S28.2E:22000:12318+2318:2320=NAR;2319=eng:2321:0:6940:0:0:0 ?

Thank you very much,
