i have been using clone cd and have no problems until now and now it will not copy it transcodes then will not write to cd and comes up with this message

Writing to video media not successful, source data to large

The writer is not capable of writing source data as requested

To write these dvd files please use "copy dvd titles" or "Clone DVD"
option from start screen.

Have the settings changed ? Can someone advise me on what to do


Thanks
