Harald,
I'm using a somewhat similar config to yours, though different receivers (PCTV Nanostick 290e for DVB-T2, and very old "WideView USB DVB-T"). I too have had problems with streaming live TV to Kodi for many, many versions. As you have noted, no issues recording, and no issues playing back recordings, it's just live TV streaming that's the problem, and usually only after a few minutes of watching, not immediately (so perhaps testers haven't noticed), and a bit worse in HD unsurprisingly. But I never see buffer or driver errors in the logs - no errors from vnsi in fact, so I think in my case it's purely a Kodi issue, perhaps something to do with PTS time stamps, and/or buffer synchronisation. It works very well, aside from live TV - just waiting for a Kodi version that solves this issue.
One of the things that the vnsi developer said to do set this in the VDR config
vnsiserver.AvoidEPGScan = 1 (http://forum.kodi.tv/showthread.php?tid=203396)
It prevents interruptions during streaming. It certainly helps, but not a 100% fix.
I don't know where PLAYERBUFSIZE is - Kodi config file - which one?
Thanks

OK - I think I have a stable configuration now, albeit weird.
- I upgraded the mobo BIOS to -latest, to no avail (hoping this would change the MSI interrupt behaviour, but it only appears to add some more CPU support. But you never know, BIOS changelogs haven't been well known for being particularly verbose.)
- I set pci=msi - no change. Will change this back to default for the next reboot
- I enlarged PLAYERBUFSIZE (and RECORDERBUFSIZE to be sure) to 50 megs, and voilà, the setup has been stable for the last 4 days or so. I know this only cures the symptom IF the buffer logic has an actual problem
OK, the WAF has been saved for now, but the fix still does not explain why the buffer overrun problem only occurs when watching live TV with vnsiserver and kodi, and can only be cured by rebooting the machine. So ... :-/
