Mark, on a side-note, besides using more memory, doesn't this approach
make your subtitles become out-of-sync?

I had a couple of clips which needed a higher vdpaubuffersize to play
correctly, but once I manually set the setting, the subtitles in (all
of?) my videos became several seconds out-of-sync compared to A/V. I
never filed a report in Trac about it, since I didn't know if this was
expected behaviour due to the increased buffer. This was btw. on
0.24-fixes+ION.

Best regards
Kenni
