[vdr] vdr-1.5.11 & subtitling problems

[Rolf Ahrenberg]

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,
