His audio issues are most likely due to the new lacing, and he hadn't
yet upgraded to the new library versions.

Unfortunately this is normal for VObSubs. VobSubs are just extracted
from the DVD and not processed in any way. Therefore they retain the
full resolution while the usual encodes crop and/or scale the video. So
the strategy how to overlay the VobSub stream with the video depends a
bit on several factors, e.g. if the playback is fullscreen or not
etc. If not (windowed) then aligning the bottom of the subs with the
bottom of the video and centering the subs horizontally might work. But
I'm no expert.

Anyway, I'm really happy that VLC will support VobSubs in Matroska :)
