log doesn't help me at all
Only thing I can tell you is that Hybrid encoded Title 3 (chapter 1-7) Job: 12_23_12_343, started the audio encoding of job 12_23_13_921 but stopped because it had troubles with the audio C:\DOCUME~1\Family\LOCALS~1\Temp\Title_5_1-7_en_aid_128__12_23_13_921_01.ac3 too small.
-> can't tell you what went wrong (see 1st post that I need to reproduce a bug)
