[QUOTE="DragonQ, post: 845908, member: 115209"] CUVID does indeed use more power than DXVA but it's also more flexible. Native DXVA2 is restricted in terms of what files are compatible. Copy-Back DXVA2 (as Nev calls it) doesn't have this restriction but it uses more CPU. I also think that neither DXVA2 mode can use hardware deinterlacing, which is the best method if you have a newer card (400 series or newer). You can force MediaPortal to only use the P8 power state (designed for video playback) of your nVidia GPU using nVidia Inspector, rather than the P12 power state (full power, designed for gaming). That way you can use CUVID with vector adaptive deinterlacing and use the same amount of power as DXVA2. However, depending on your card's abilities, this may stop you being able to play some high bit rate 1080p files. [/QUOTE]
