Well I didn't get any replies :) so replying to my own message in case it
benefits someone else with the same problem (I've seen this error posted a
couple of times this year in gossamer threads.

Well I changed my Nvidia GeForce 8500GT (256Mb) to a 9400GT (512Mb) and it
looks like the problem has now gone away. VDPAU now initializes correctly
everytime I view Live TV or a recording. So I can only surmise that the
issue was lack of memory on the video card. Mplayer seems to get away with
only having 256Mb of video RAM but Mythtv seems to want 512Mb to play with
VDPAU without any hiccups.

Also interestingly I did some tests using qvdpautest and found that even
though the 8500GT trumped the 9400GT in some of the tests..... I CAN RUN
Advanced 2x (HW) deinterlacer on 1080i content !! and its soooooo smooth
:) absolutely brilliant. Results of the tests are below:
