AMD or NVIDIA
CraigNZ:
Actually, v104 HW acceleration worked, v108 it locked up the program, so I had to turn off HW acceleration. Given the comments above I will swap out the AMD card and try the 650. Will report back here later today.
CraigNZ:
I swapped the AMD card for the NVIDIA card (GTX650ti) and after resolving the audio problems everything worked perfectly. I can now use v108 with HW acceleration. But more importantly I was totally amazed by the difference in quality. With the AMD 5700 board the text on the screen was fuzzy .. am using a ONKYO AVR and Panasonic Projector. With the new 650 card the text is crisp and the entire viewing experience is WAY better than I had ever seen it before. This surprised me because I thought the information was completely digital and with all processing turned off the video signal should be identical with either card. But it is night and day. Both cards used the same settings in the JRiver software. Both cards had all enhancement processing turned off, ie, all settings deferred this back to the application. And on the AVR I am using video pass through. So there should be no difference. Only other thing I can think of is the NVIDIA uses a different HDMI cable because of the smaller connector as compared to the AMD card. So maybe the HDMI cable made a difference, but again, if passing digital information I don't see how there could be such a difference. Or, the NVIDIA card is doing some processing to the digital signal that the AMD did or vice versa. In any case I would highly recommend the 650 over the 5700 card.

For what it's worth, it was probably a difference in the default output mode on the two cards (one using RGB and the other using YCbCr for example) rather than the card itself affecting the sharpness, or it being the cable/adapter.
It is all digital, and sharpness of text should be unaffected by those things.
CraigNZ:
That could be .. if that is true then I would have to say NVIDIA did a much better job at setting up the defaults 'out of the box' then AMD.

Glad you now have a good result!
