DVB Link iptv 4.0 still stutterings on HD channels

Postby timofort » Wed Oct 19, 2011 3:22 pm

Hi !

Since I upgraded my DVB Link for IPTV from 3.2.1 to 4.0, I have seen no change for my problem.

With 3.2.1 as 4.0, I have regular stutterings on IP HD channels (with H.264) (every 10 to 30 s.), like Brava HDTV, Mezzo Live HD, even France Television HD or Arte HD which are no crypted public channels (I'm living in France and my ISP is Free ADSL).

It's a new problem because I had no trouble several months earlier with these channels.

No change with uninstalling PlayReady for WMC.

Task manager show no huge running process.

My Internet connection gets 12-13 Mbps download (ADSL2+) and there is no other running Internet service during event.

With VLC on the same PC, there is no stuttering with the same IP HD channels.

My hardware configuration is : Core 2 Quad, 8 GB DDR, nVidia GF GTS450, Windows 7 Professional x64.

Thanks.

Hi realman.

This is the link to a Mezzo Live HD stream on my computer.

And this is the link to a Brava HD stream on my computer.

Try setting server priority to Real-Time. This should help you.

Hello Oberon

When I set server priority to "real-time" and do a save configuration, it comes back to "high" the next time I open server configuration.

Same problem with IE9 as well as FF4.

The only thing to set this value consists to open dvblink_configuration.xml with notepad as administrator, and set "server_process_priority" item with value "256" instead of "128".

Even with this new value, and after a PC reboot, and verify server configuration is in real time in browser, HD channels continue to sutter every 10 to 30 sec.

Can it be that refresh rate of your TV is at, say 30 Hz, while incoming stream is at 25Hz?

Hello.

According to my Internet & IPTV Service Provider (Free/Freebox), it broadcasts its IP streams at 30 Hz, and my display refresh rate is 30 Hz too.
