Hi gang,
 
Having a bit of trouble, and need your wise guidance.
 
I just build my first HTPC.  Here are the specs:
 
The PC:
EVGA GT 240
Antec EarthWatts Green EA-380D Green 380W
ASUS M4A785-M
LG Black Blu-ray Disc Combo SATA Model UH10LS20
SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM SATA
AMD Athlon II X2 250 Regor 3.0GHz
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2
PowerDVD 10
XBMC Media Center
 
 
The Television:
LG 42" 120 Mhz LED
1920x1080
 
Here's my issue:
 
All content, BluRay, HD or not,  plays choppy (Not skipping), ie like the refresh rate is too low (It's set at 60); also, unfortunately, I can't seem to raise the Refresh Rate to 120. 
 
I never had this problem when video was streaming via USB cable in either the LED, or the LG BluRay BD590 player I was using that this replaces.  All content played well.
 
I'm using the latest nVidia drivers, and I'm plugged in via high quality HDMI cable..
 
My question is this:  Any way that I can fix this?  Or am I using the wrong card?  If so, which one should I be using?
 
Thanks again!

Past 20usd on monoprice... there is no reason to get a "better" HDMI cable unless if it's 12AWG and 100' long :p

Anyhow, the tv you have does not accept a 120Hz input. It takes a lower frequency signal and doubles up on the frames, basically uses an image processor to give the appearance of true 120Hz (it is refreshing @ 120Hz, however, it's doing that with a bit of processing and at most, a 60Hz input).

Are you plugged in via a HDMI port on the card, or via an adaptor?

Finally, what is the frame rate of the source material? Some, like 23.96, are a bit messy :p

 
Thanks for the quick response!

Some of the source material is a bit messy, but the Blu-Rays (I tried Ironman last night) look a bit choppy as well....

Okay, I did a bit of research. I gotta go soon, but here goes:

Nightly builds use GPU acceleration. Current stable release for windows uses the CPU for video decoding.

If you are willing, test out a nightly build compiled alreay, here:

as for PowerDVD, I have no clue :( I'm sorry.

Dude.   You're the man.  I'll give that a shot tonight, and get back to you tomorrow with results.
