I was able to reproduce the problem with my setup here with the
following config:

 * Nvidia Quadro NVS 135M (G86)
 * 256 MB GPU memory
 * Nvidia 195.30 driver
 * Temporal 2X (w/ skipchroma)

Before the new VDPAU rendering code was committed around changeset
[23235] the video plays flawlessly and afterwards the video fails to
keep up with the audio and results in massive frame drops like you are
experiencing.

Not sure if it matters but how much GPU memory do you have allocated
on your ION?
