Hardware Dual Video Decoding. Do I need it?

[hendra]

When I tried to run Cyberlink BD Advisor, http://www.cyberlink.com/prog/bd-support/diagnosis.do , it said that my ATI HD 3470 passes the basic playback capability but fails advanced playback capability.

It said:
Hardware Dual-Video Decoding Capability for H.264: None
Hardware Dual-Video Decoding Capability for MPEG-2: None
Hardware Dual-Video Decoding Capability for VC-1: None

Although it passes test for Bonus View, BD Live and Network Capability.

A search at Cyberlink site reveals something:
Hardware Dual-Video Decoding:
Blu-ray Discs use a different video compression, than MPEG-2, H.264 or VC-1.
Some graphics cards have the new feature that supports hardware dual-video decoding.
But not all of graphics cards can support HD (High Definition) decoding of different video streams.
The CyberLink Blu-ray advisor will test the Dual-Video Decoding Capability of your graphics card for each of the video steams, and displays the results in the Advanced Playback tab.


Do I really need Hardware Dual-Video Decoding? Which movies that use it?

Do you want/need the Picture in Picture at HD resolution?

This original BD laptop has a nVidia 7600GT in it - I get the same results from the advisor.

I have no need or want for PiP that's in HD.
My other laptop will do it, but I have never used that "feature".
