Hi,

when I want to watch HD recordings on my main TV (Kodi 14, OpenElec, RPi2) it's impossible via the TV function as it stutters, looses the audio etc.
DCPU is close to 100% on the Raspi.

But when I play the same TS file on the same Raspi directly from the NAS via SMB, all is smooth and the DCPU on the Raspi is around 10%.

Any ideas what might be the problem here?

I'm using TVH 4.1-1163
