60 is result of the DXVA hardware deinterlace. Usually software interlacing is wither bob or weave (if you aren't using something more advanced from ffdshow for example) and by design those two deinterlace modes are only able to provide the 30fps.

Thanks tourettes. Is there a software deinterlace in ffdshow that would provide the 60fps? I can try that out and see if my CPU can handle it. If it can't, then maybe I'll finally shell out the $$$ for a new video card.
Andrew H,
Have you done any H.264 DXVA? I have an HD-PVR connected to my cable STB and the resolution locked to 720p. I'd like to lock it at 1080i and get the 60fps with the DXVA with a N9500GT. I'm curious to see what your results are.
If you need a clip, let me know and I can upload one for you if you don't mind.

I don't have any .264 material that I know about because (as we both know) ATSC is mpeg-2 and not .264. I have some .mkv files that are pretty large resolution (looking at Options from inside MP-HC) and they play just fine... although I suspect they are not interlaced. The fact is I had no issue with the .mkv files before the 1.0.1. interlace recode (the subject of this thread) but have mentioned how much less CPU using the .264 MP-VideoDecoder over the PDVDx that I had been using. I'll guess they will not allow a large post on here but if you have a host, post the link and I'll try it on my system... I suspect it'll be no problem because I'm fine on mpeg-2 at 1080i aside from the additional decoding of the .264
Maybe someone can address whether there IS such a thing as .264-encoded, interlaced video? I suspect the HD-PRV may deinterlace on the fly before performing the .264 encode. Anyone?

HT2 vs HT3 CPU only effects onboard video memory speed.
HT2 vs HT3 CPU has no effect on a seperate video cards.
Modern AVCHD format digital camcorders normally record in 1080i (AVCHD uses H.264 video compression). I have a few short AVCHD 1080i clips which play fine via my 9500GT using DXVA (PDVD7 build 4617 H.264 codec).
There are also some 1080i and 1080p 50Hz/60Hz test patterns in MPEG2, H.264 & VC-1 formats here - HD 1080i Test Pattern to determine Vector Adaptive Deinterlacing + others icl. Ticker - AVS Forum

Yes, there is such a thing as .264 encoded interlaced material. The format I receive from the HD-PVR is 1080i. Again using Cyberlink PowerDVD 9 H.264 codec, I can get 30 fps with software de-interlacing. My goal is to get it to 60 fps. If you'd like, I can get a 1080i sporting event recorded from my HD-PVR for you to test with. I don't think the samples posted above have a 60 fps 1080i recording.
I will make a short recording and post it for you. I'm at work now though, so it won't be until tonight. I appreciate your help!
Yes they do - the '1080i 29.97 fps' files are 29.97 frames per second, 59.94 fields per second interlaced video. Assuming a 1080p 59.94Hz display, this will be hardware de-interlaced to 59.94 frames per second.
(people tend to talk about 60Hz/60fps, but in reality '60Hz' video is normally actually 59.94Hz video)

Andrew H & Owlsroost, I've also uploaded a 1 minute clip of a 1080i H.264 encoded hockey game that I recorded with my HD-PVR. Let me know what FPS you get in MediaPortal playing it. Thanks!

I went ahead and bought a ZOTAC GeForce GT 200 1GB GDDR3 card ( Newegg.com - ZOTAC ZT-20201-10L GeForce GT 220 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card - Desktop Graphics / Video Cards ) to see if it works out. If not I can always return or sell it on eBay.
