Hi janbar,

thanks a lot for your work. Something that currently prevents me from using this plugin on a daily basis is that i observe picture corruption about every minute. The picture does not stop oder stutter but only builds some blocks and continues to play.

If I skip back and watch the same scene again, it does not happen anymore. If I'm watching some seconds in timeshift (after skipping back) it never happens. This only seems to happen if I am watching near-live.

I suspect that the data from the backend comes late and this now has an effect as the whole stream setup is faster.

Unfortunately, the debug log does not show anything when this happens.

My setup:
mythtv HEAD of 0.27 branch
xbmc HEAD of gotham branch
pvr addon HEAD of gotham branch of your repository

mythbackend is on a separate system and storing its data on btrfs (i suspect this could cause delays)

Are you aware of such an issue or do you have an idea on how to analyze it?

You should have message like "read ahead" in log. Meaning addon cannot read more data and then it wait 100ms. So after few times the timeshift grows and you should no more have the issue. I bold the thing like that.
Otherwise your player could read to fast (bad synchro) because it drop frames with errors: Here it could be due to signal quality.
Finally the backend could be too slow to write data to the disk: btrfs ? Here i use ext4 with mount options below (important !!!):

UUID=1f314843-0ab1-4dee-9e89-562446549eae /local ext4 noatime,nodiratime 0 2

Storage for livetv, recordings etc... are within /local and mount options are "noatime,nodiratime" to avoid update of access time on each read/write operation !!!
