any progress? just tested latest kernel 4.13.12 on x86 +S950 and it's still affected
Looks like it's I/O dependent: the problem manifests after tens of minutes when just displaying DVB stream (cca 90mins) but with heavy disc I/O in serveral minutes...
EDIT: reported upstream: 197835 – DVB-S discontinuity, PES packet size mismatch, stream corruption
