OK, done a fresh install with all the same plugins and backup has worked fine with TS Flashbackup so don't know what was causing it. Thanks for comments.
OK, flashed a new image on and created a backup using TS Flashbackup and it worked. Added cooltv and channel list and created another backup and it worked again. I will add 2 plugins at a time and backup and if it happens to cause error somewhere, i'll post the affecting plugin incase anyone has the same issue.
