Itunes 12.7.3 still not burning full playlists

I have read many posts about iTunes not burning playlists to cd and Apple tell me there is no iTunes update scheduled to possibly resolve overcome this issue. The burn begins but after 2 tracks the time remaining increases instead of decreasing and eventually fails with an error message. I know my tracks are ok as I have an older iTunes version on a Mac Book and they all work! Does anyone have any further info on this issue as it's beginning to drive me mad and although I have discussed it with Apple support and in-store nobody at Apple seems to give a monkey's toot!!!!
