Same here with my digital devices cine S2 (10 tuners, 3 active atm).

It looks like, that the problem is triggered by background searching and switching becaues if I use the 3 active tuners to receive 3 different sat streams, there are no disruptions. Maybe this information can help.

Another info: setting "idle scan muxes" to "false" eliminates the disruptions.

Thx for the input.

I looked in the webgui of TVH and I already had the Idle Scan Muxes under DVB Inputs->Networks set to "False".

This seems to happen for me too only when background searching or background EPG updating is going on and TVH therefore uses more tuners.

I have also Digital Device Cine S2 (two cards with 4 tuners so totally 8 tuners).
My tuners shows 80-85% SNR and 70-80% signal strength which is very identical with the actual measurements I get when I measure with a DVB-S tool (SatLink WS-6926) so it should not be that I have bad signal or cables.

I am now running with two computers connected to TVH and watching 2 channels and recording 2 other at the same time and no continuity counter errors at the moment (however, no EPG updating going on either in the background)

I have also Disabled the "Force initial EPG scan at startup" that can be found under Configuration->Channel/EPG->EPG Grabber

I had the same issue when (OTA) EPG scanning was active on a free adapter: missing packets disrupting the HD stream I was watching. I am currently not sure if the issue was caused by tuning of the other adapter, or the EPG scanner, but when I selected "skip idle scanning" the disruptions disappeared.

Hi

I just wanted to clarify that I have found the (possible) reason for my continuity counter errors that I see on some of my DVB-S2 channels on the THOR satellite for Canal Digital Nordic channels.
I have mostly seen these CC errors on for example channel "TV3 HD (S)", "BBC HD" and I would probably have seen similar CC errors on other channels as well.

My tuner setup is 2 times of the Digital Devices Cine S2 cards with DuoFlex S2 added to the expansion port, i.e. 4 tuners per card, totally 8 tuners into TVH.The cards are all of the latest version 6.5 with the latest firmware (NOT the ngene-based cards that were version 5 and 6, my version 6.5 cards are displayed as "ddbridge" in the kernel)

(Card info at http://www.digitaldevices.de/english/Cine_S2.html)

I am using the latest driver from http://linuxtv.org/hg/~endriss/media_build_experimental.

The reason for these CC errors are NOT driver based and NOT caused by TVH as far as I can see now after extensive testing of both TVH and checking ALL my eight incoming DVB-S cables from my 8 port LNB.

I have checked all signal cables at the connector end that goes into my tuner cards with a SatLink WS-6926 satfinder/meter tool (http://www.satlink.de/satlink-ws-6926-hd-second-edition.html).
I get signal strength around 89% according to my meter WS-6926 and signal quality 80 to 81% continously on all channels and ALL 8 tuner cables. I have even logged each cable for approx 5-10 minutes and no signal or quality drops what so ever.

I was really wondering why I would get these CC errors.Suddenly while I was watching the TVH GUI under "Status" and being confused about these errors, I could see that when TVH started to use my tuner number 6 I would get CC errors?!

I checked the cable again and signal was as good as previously. I switched signal cables between tuner 5 and tuner 6, still CC errors as soon as TVH started to use tuner no 6?!

So it definately looks like a hardware error on one of my tuner cards!

The quick solution was to just disable that tuner from TVH under the configuration tab for tuners and I haven't had those CC error problems since then. :-) (Of course, I get small CC errors sometimes when switching channels but I consider that as fully normal. I get also CC errors if there is VERY heavy rain and I consider this also normal since I am not at a 90-98% signal/quality strength during normal weather.)

I will try to replace the tuner card that seems to have one of the two tuners broken/bad shape and see if a new tuner card will work better. I think I am still under warranty. :-)

I´ve found out that it is NOT the tuner cards that are broken (at least what I think)!
