I've tried it in my production machine now, which has this card:
03:00.0 VGA compatible controller: nVidia Corporation GeForce 8400 GS (rev 
a1) (prog-if 00 [VGA controller])
        Subsystem: Giga-byte Technology Device 3463
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at ea000000 (32-bit, non-prefetchable) [size=16M]
        Memory at d0000000 (64-bit, prefetchable) [size=256M]
        Memory at e8000000 (64-bit, non-prefetchable) [size=32M]
        I/O ports at b000 [size=128]
        [virtual] Expansion ROM at eb000000 [disabled] [size=128K]
        Capabilities: [60] Power Management version 2
        Capabilities: [68] Message Signalled Interrupts: Mask- 64bit+ 
Count=1/1 Enable-
        Capabilities: [78] Express Endpoint, MSI 00
        Capabilities: [100] Virtual Channel <?>
        Capabilities: [128] Power Budgeting <?>
        Capabilities: [600] Vendor Specific Information <?>
        Kernel driver in use: nvidia
        Kernel modules: nvidiafb, nvidia


And while vdpau does work now, I get little CPU improvement (drops from ~60% 
under xv to ~45% on vdpau), there's some tearing during action scenes and 
some image freezing for a few seconds when switching from live TV to 
recordings which I've had to "kill" on occasion.

Currently I only have SD content to watch and my Sony Bravia 32V only 
supports up to 1360x668.  Any point using vdpau?
