RPi(OSMC) with PVR client and cache problem

Hello,

I have Raspberry Pi Model B+ with 5V 2A power supply. 500 GB external HDD connected with 2 USB and works perfect. My internet connection is about ~72Mbps and the Pi is connected via cable.
I have OSMC latest version installed on it and on my Windows 10 desktop computer too. And now for the problem:
I have some m3u file with some TV channels. There are working and streaming more then perfect on my OSMC desktop version. But on the Pi i see only pictures (simple PVR client), but the sound is perfect.I made some changes on my advancedsettings,xml file:
advancedsettings>
network>
buffermode>1
cachemembuffersize>0
readbufferfactor>30
/network>
pvr>
minvideocachelevel>30
minaudiocachelevel>30
/pvr>
/advancedsettings>

/I deleted all “<” in the code because it is hidden in the preview for the forum./

When i am watching some channel the LED on my HDD is not blinking like for read and write, but it does when i watch some movies that i have on it. I am 99.9% sure that it is not Internet connection problem.
I hope that it can be fixed. Thank you for the help.

You have MPEG2 codec purchased and installed?

With RPi1 you need to purchase the MP2 codec license!
With RPi2 some movies will work with just the brute power of 4 cores, but the higher the interrupt load, the higher the risk of video stuttering comes.

In my setup, (no local movie disk, no WLAN, just ethernet and SMB) a lot of movies in SD resolution (540) where fine, some more in HD-ready (720) too, but it depends on the video format. Thus, i purchesed the MP2 license also for the RPi2’s. Now it’s fine for all 540, 720 and most 1080.

No i haven`t yet.I have to purchased it then, but first i will read how to do it because i am not sure how to do it properly.

Now it works like a charm. Thank you for the answers. Have a nice day!
