They aren't issues being seen by Isaac, rather Isaac was told by his contacts 
on the driver team within Nvidia that they had to be removed because they 
break VDPAU. Their algorithms are not designed to work with 1x 
Temporal/Advanced deinterlacers.

Nvidia had been seeing a lot of bug reports from MythTV users using these 
deinterlacers and apparently were "confused" because they are not official 
VDPAU deinterlacing modes.
