I installed dvdfab 8.0.9.8 and began having issues converting blu-ray discs. Any time I attempted compression, mostly with making MKVs (however I had the same issue compressing a full disc in Blu-Ray Copy mode), my blu-ray burner would basically stop responding at the compression phase and just hang there. I have a LG WH08LS20. I went back to 8.0.9.2 and the compression is now doing just fine.
