after testing, now its working perfect, changing is fast, and also the load of the channels are very fast.

.6 or .5 also?

5 did not, only 6 is working perfect
with playback set for this
Engine= ProgDVB Engine
H.264 channels playback= OMX.MS.AVC.Decoder
channels playback mode = OMX.MS.AVC.Decoder
H.265 channels playback = OMX.MS.HEVC.Decoder
MPEG-2 channels playback = FFMPEG

Thanks!

you welcome, but what was the issue that made it to be like this? because it was working before perfectlly for me was it because i updated my TV ?
