Hello,
I've build a new VDR with h.264 xineliboutput plugin software decoding
and got a problem now with
buffer overruns and distorted recordings on all HD channels:

This occurs with both saa7146 and mantis pci tuner cards.
This has not occured with the old VDR system using Broadcomm's crystalhd decoder in libxine.
I've FIXED it.
Not yet. It occurs again after some days system uptime.

Cause was HW unsupported pci hotplug damaged motherboard pci bridge and/or removed antenna signal amplififier.
No. dd write speed test showed a regression in the 3.12.40 AHCI SATA driver, HDD write performance dropped down from 60MB/s to 4MB/s on the which is too slow for HDTV or multiple recordings.
After reboot full speed is back. I've upgraded the kernel to the last longterm 4.19.324 stable version to check if this resolves the issue or it is a hardware issue of the
