Thank you @Warner360 yesterday files are making it absolutely fine from the server no issues at all.. Shall I try out 64bit Kodi DSPLAYER? I noticed that my sound is ever so slightly out of sync now for some reason...... Hmmm I choose sanear as the audio and wasapi.. Hope this is correct
Also sorry if this is a silly question but what benefit will I get from creating separate profiles?.. I only have 1080p and 4k movies h264 and h265 nothing else..

 64-bit DSPlayer won't change anything and could actually make things worse. The sound sync could be your AVR. Sanear and WASAPI Exclusive are the correct choices if bitstreaming (provided you selected allow bitstreaming). If bitstreaming, use whatever works; whatever you were using before. You need two profiles. One for 1080p and one for 4K. One uses image upscaling and the other doesn't. So you want to maximize everything for 1080p and maximize everything for 4K. You only need to worry about the settings under scaling.

My guide covers how to create profile rules. Your rules would be as follows:

if (srcWidth > 1920) "2160p"
else if (srcWidth <= 1920) and (srcHeight > 1080) "2160p"

else "1080p"

Create two folders under scaling with the names "2160p" and "1080p". Paste the profile rules above.
