After I upgraded to 3.9.1949 and newer I started to see DTS discontinuity errors in the tvh-log for some HD channels using Dolby Digital 5.1 or 2.0 sound:

Note also the "timediff" error in the log?

switching to another HD channel:

I initially thought this happened only HD channels with DD 5.1 sound but I have seen this on HD channels with 2.0 sound as well.

I can see that channels like TV4 HD, SVT1 HD, SVT2 HD works fine without getting DTS discontinuity erros.

I have not seen these type of errors in versions before 3.9.1949.
