Here's what ogle says when I have doublebuffering Xv in 24bpp:

Debug[ogle_vout]: resize: 720, 540
X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  141 (XVideo)
  Minor opcode of failed request:  19 ()
  Serial number of failed request:  45
  Current serial number in output stream:  45

For smaller videos like my webcam, the same error does not occur.
Perhaps there's something else I can change to fix the error?
