thanks Warner, now my system is configured with "DVXA2 (copy-back)" in the LAV video filters and in madvr in "general setting" use Direct3D 11 for presenation and sincerely I'm finding it very well, with fullHD material (1920X1080p) is all good, the "rendering" average and max are always quite low, about 10 and 11 ms, no droped repeats delayed frames, DSplayer is no longer stuck at startup, and my GPU is only a modest AMD rx 560 ASUS STRIX OC !!!! my intention is to buy a more powerful GPU for the 4K HDR (SAPPHIRE Radeon RX 580 8 GB PULSE) shortly buy a 4k oled tv.
Thanks for the good advice and merry Christmas to all.

 Personally, I think the RX 580 is a hot and noisy card. Something to keep in mind. 

its noisy cos its hot

yeah mine is very noisy but most cards are when really pushed. I knew this going into the purchase. I actually makes sense to buy the fastest card you can for the money have, then run it medium settings to keep it cool and quiet. If I keep mine under 60 degrees the fan doesnt come on.

I've now dropped down to NGU low for upscaling and chroma, to keep things quiet, my old 460/560 used to run hot and noisy with these settings where the 580 runs completely silent.
