Yes, you are correct that the number is not reliable (VDPAU frames cannot be dropped in MPlayer like software-decoded frames). The important thing, however is that it is not possible to keep A/V sync (for both our G210 and GT220), but that actually the lag gets bigger every second. That is at least for MPlayer svn, I did not test xine.
I will probably not look into this again, the important thing imo is that it is not possible to decode 1080@60 H264 and keep A/V sync (at least for the cards we tested, I don't know about the GT 240).
