So from my understanding laptop/pc with dvb tuner to sat,Tvheadend on dedicated server and I can pull in channels to the server..thats the basic start I'm understanding.

If you are describing the following :

PC/Laptop with USB or PCI/PCI-E DVB tuner running TV Headend (this handles tuning, recording, EPG etc.) This runs a web interface for configuration and allows you to schedule advanced recording schedules from the web UI.

Kodi client with the TV Headend PVR add-on - which handles viewing Live and Recorded TV (and allows browsing of the EPG and basic recording scheduling) running on another platform.

Then yes - that will work.

You can also run TV Headend and Kodi on the same device - but most of us recommend not to do this. You can also run TV Headend on some NAS and other Server platforms (unRAID). For a simple single-tuner Freeview HD set-up in the UK a Pi 3B+ or Pi 4B with a Pi TV Hat (which were available for around a fiver on Amazon at one point) is a neat solution for a standalone solution.

You can also get DVB tuners that connect to TV Headend over an IP connection rather than USB/PCI/PCI-E - such as the HD HomeRun Dual and Quad DVB-T/T2 tuners and SAT>IP satellite tuners (available in dual, quad, octo and more tuner variants) My current set-up is based around these. (The IP-connected tuners work particularly well with NAS/Server based TV Headend setups, or a small TV Headend install running on a Pi 4B, as you don't have to worry about the server/NAS/Pi having driver support for specific DVB tuners)

Thank for the more in depth reply mate.

so ive got the basics running with a few minor things i cant seem to work out.
At the moment ive got it running over home network,raspberry pi at router and viewing over ip on kodi on tv..so all good..except a couple of channels which are pixelated and wont play,but not a worry at the moment..On a single tuner so limited.Also not sure why bu the epg doesnt seem to work??.There is about 3 channels that pull epg

Im interested more in being able to watch outside of the home...ie: when im away as we do have property abroad.
I understand there are other options but id rather use my own set up.
Also is there a way i can set to use on anything other than kodi..apps such as tivimate.

Any advice or guide for viewing outside of home network would be great

Thanks

What region are you in?  What DVB source are you watching?  Different platforms have different EPG standards that need to be enabled in the EPG config panel.
