Performance of Zotac ION is quite poor in interlaced hd movies. My HD movies comes from Sat, recorded by VDR or TVheadend.
Movies come from, Cinemax Eurosport HD or HBO HD.
I have tested on last builds of PVR Openelec, on pre-build images, also from my own compilation from latest github sources. Also on latest stable 1.0.2 version
I've tested in 2 resolution 1280x720 and 1920x108.
In first case performance is good, but in the second not quite enough.
Other movie settings are Bob, telecine, Auto ION Optimized in Interlaced menu, i've teste all of them, the best results on Bob settings but not enough.
I've heard ION isn't good in deinterlacing but I think isn't true. Under Vdr+xineliboutput+vdr-sxve+vdpau _ib the movies are smooth in all resolutions an in BOB setting.
I also tested under special vdpau testing tool qvdpautest, with success
And what about Openelec + xbmc? What the diffrences in VDPAU implementation on both software platform?
Is there any chance to have good performance on ION platform with sat interlaced content?
Zotac IONitx-A, 1GB Ram, 16GB SSD
