Hi,
I'm having heavy artifacts with the new vdr-1.5.11 in finnish DVB channels. The picture freezes now very often compared to previous VDR version (I reported about the same rare problem in vdr-1.5.10) and it seems that the problem is the new SUBTITLE_PACKS size. I reverted it back to 2048 and haven't noticed the problem after that.
During the freeze VDR's transfer buffer gets full and VDR is clearing transfer buffer to avoid overflows. This happens only on channels with DVB subtitling.
I'm using 4MB FF card as a primary device, if that makes any difference.
BR, -- rofa
