I have used P-III and ATi Radeon HD2400 with XBMCBuntu and 1080p h264 media files + bluray disks over hdmi, it was smooth as butter (video+audio) and it worked with Windows XP as well, also Nvidia Geforce 7600GT can playback h264 @ 1080p with hardware support.K6 can playback dvd and divx/xvid codec very well, i did run big bug bunny h264 720p with Win9x, it did run, just without extra videocard support and it was slideshow.

After Pentium 3 Tualatin - HD Playback Machine i used these two AMD PC for my Media Playback.

I have used P-III and ATi Radeon HD2400 with XBMCBuntu and 1080p h264 media files + bluray disks over hdmi, it was smooth as butter (video+audio) and it worked with Windows, also Nvidia Geforce 7600GT can playback h264 @ 1080p very well.

Win9x and NT should be supported, i used it with Win98se.
I have used mpf with this mplayer version (3dnow support).

K6 can playback dvd and divx/xvid codec very well, i did run big bug bunny h264 720p with Win9x, it did run, just without extra videocard support and it was slideshow.

Thanks but P-III has SSE, K6 don’t.
That is why I am asking.
I am trying not to see a slideshow, that is why I am asking for a video player tailored for 3Dnow also and not ONLY SSE.

Not sure what to say about your post, thanks, but it is not helping much.

Anything media-related that was optimized for 3DNow! or used it in any capacity likely had the code removed years ago and moved on with regular SSE/MMX, as 3DNow! never caught on and was mostly used for experimental stuff in gaming and media and was gone by the Windows XP days, whereas MMX/SSE stuck around.

I have posted you mplayer with gui that has 3dnow support, i see it should support Windows NT OS as well (like XP is), H264 DXVA videocard support maybe missing from it and you need it for all slow and old cpus, without it, it will be slideshow for h264 1080p, did you try it out?

(Mplayer was a no go)

mplayer is a go, but you have to compile it yourself with appropriate flags
you could also try mpv

It is full of bloatware…

A mini PCIE card based on the Broadcom BCM970012 or BCM970015 decoder card might be an option

-if it can work through a PCIE to PCI bridge
-if its drivers do not require SSE
-if you don't consider this "cheating" somehow
- if you can find one at a good price

Already tried, it won’t work on any SS7 motherboard I have (even pci 2.2 mvp4). PC freezes.
It starts to work from S370 motherboards.Dunno why.

I'm pretty sure if you dig up an old enough version you can find a Media Player Classic that doesn't require SSE. I used it on a K6-3 in the early 2000s.

K-Lite Codec Pack 3.45 supports Win98. Maybe it has DXVA-HD support.

Will the video drivers allow H.264 acceleration without even SSE1 though....
