Comment 8 for bug 852345

This patch looks suitable to me for backporting to natty as an SRU. If anyone would like to see this done, please test the ~natty package in the PPA from my prior comment with a sampling of DVDs which had been working properly before (I don't need to know the names, just tell me the number of different ones tested). If this is seen to cause no regressions, we can try posting it for SRU to natty in a few weeks.
