Changed my mind and decided to go with the link provided by MAT ALAN,
To be honest I’m not at all sure what I did but I tried to restrict the download to the minimum of changes in the hope of restricting any potential damage. Near the end of the download it reported two broken links to files in the registry and recommended deletion, followed the advice and I can now play DVD’s.
That’s 50% of the problem solved but I’ve still got jerky video in IPlayer, Utube etc. I know the answer is in the K-lite pack somewhere if only I knew where to look. So if anyone is an expert on this programme then any advice would be welcome.
I would have downloaded the full K-Lite from file hippo and left everything as default. The jerky playback from streamed videos suggests to me either a flash problem (doubtful) or a browser problem. You don't say which browser you use so if you use IE then try firefox and download the non-IE flash player, from file hippo again. Use IE to download the non-IE flash player making sure firefox is closed. It could be an addon in your browser causing a conflict.
Installed FireFox and the improvement to Google earth is dramatic.
Unfortunately no improvement to IPlayer or other streamed video Possibly rdave13 was correct and I should have run K-lite at the default settings. When I pluck up the courage that will be my next step but meanwhile I'll tick as resolved.
Many thanks to all who helped
