Tvheadend

Hello,

I use TVHeadend on my Synology DS415+.

Unfortunately, I get the transcoding TVHeadend not to run properly.
I want HD channels can also look with a bad Internet connection, for the video signal is to be transcoded/compressed.
I have tried different streaming profiles or adapted, unfortunately all without success.
The problem is always that that video signal then increased. The RAM, CPU and hard drive are always not busy while the image increased.
Without transcoding it runs in its own LAN without the video signal increased.
Has anyone transcoding run successfully and perhaps can give advice?

best regards

Robert
