It is but it appears there arnt any for sale anymore on the sponsors site. Unless the et8500 tuner will fit the 8000.
This is what you want : https://www.amazon.co.uk/Xtrend-DVB-.../dp/B00K5JAWKE
But none available on amazon either. There are other places you can get them from but i dont want to link them on here, just google et8000 cable tuner.
