[SOLVED] Problem with PVR-500 and Media Director

[pw44]

Hia,
today i changed the PVR-150 (1 tuner) by a PVR-500 (2 tuners). After i did it,
i can watch TV (tuner 1) on my core/hybrid and watch TV (tuner 2) on my MD.
But there is something weird going on. On the MD, while watching TV the image and the OSD freezes for a large time (more than minute) when i get the menu (F7), becoming unresponsive. After it responds again, each key i hit make the same behavior happens.
It only happens when watching TV.
Did anyone experienced this problem before?
TIA,
Paulo

Did find out what was happenning:
I did configured mythfrontend to use "vdpau" profile. It hanged the MD. Setting the profile to "normal"  solved the problem.
The strange is that on my core/hybrid, using vdpau profile did not cause any problem.
The core/hybrid and the MD have the same motherboard (ASUS 3N78-VM).
But anyway, having the profile setted to "normal" on both (core/hybrid and MD) seams to be the best way for me.
BTW, i did read the wiki about setting vdpau in mythtv, tried it, but did not help.
