I tested this patch with my single Technotrend DVB-C Premium 2.1 card +
Conax 4.00e CAM and "not-so-vanilla" vdr version, with vdr-1.3.36 and
dozen of plugins and patches to those.

Not that I can give you any hint, only report what happened...

Recording another and watching another encrypted channel at the same
time is possible, but gives very much same distortions as you described.
Recording is jumpy and the livestream hangs in ~1-2 second periods.

Hope that I can help somehow.
