[mythtv-users] 8400GS -> GT 430 -> ?? (60Hz, VDPAU High Quality)

[Evuraan]

I run 0.23.0+fixes24158-0ubuntu2 (cant upgrade yet), on ubuntu 12.04
lucid, and was using an nvidia 8400 GS, (vdpau slim), and went to
nvidia GT430 (VDPAU High Quality) two days ago after
http://www.mythtv.org/wiki/VDPAU seemed to qualify GT430 as a decent
card.

(1) Now that I look in the mailing list archives, there seems to be
talks about GT430 having issues in 60Hz countries, (I live in one,
US),
(2) I was getting tons of "NVP(6): prebuffering pause" messages, but
setting vdpaubuffersize=32 improved the situation
(3) I still experience random pauses while playing 1080 OTA
recordings, and with these corresponding entries  in my log
     2012-06-09 13:35:16.303 WriteAudio: buffer underrun

Considering those, and that I can return the GT430 w/o $$ penalty and
get/exchange_for a better & suitable card, I wanted to reach out for
suggestion.

What's a better(!) card for use in the USA, I am looking to use VDPAU
High Quality?

I am sure some of you went this trail  before me, your suggestions
will be much appreciated.

Many thanks in advance.!
