Hello all,
since I upgraded from Ubuntu v12 to v14 and to nvidia 9800GTX2 I can't
view livetv any more in quality.
I get distortions in the mpeg streams sometimes even no audio. This
happens round about every 5 - 30 seconds.
It is the same mysql-database and the same configuration as before.
I don't think it could be performance related, as CPU's are below 20%. No
IOWait in top. Slowdelete activated.
I have got DVBS2, driver is vdpau.
I also tried different deinterlacers and even deactivating it, no change.
I haven't found any mpeg related error in the log, only strange entry is
about unknown AFD ID's, but I am not sure, if that's related.
Another interesting entry is: "[dsmcc] Dropping block size 4096 with tag
21, carouselID 11, dataBroadcastID 0x123"

If you can give me some advice, how I could narrow analysis down, that
would be great?
