Thanks for responding. I have just checked the logs, and the problem is not mentioned. I should note that where the problem arises, the track listing starts as:
0 >> Disc 2 (followed by a timing)
0 >> Disc 3 (followed by a timing)
1 Track 1 (from Disc 2)
1 Track 1 (from Disc 3), etc.

There doesn't seem to be a problem if the two discs involved include Disc 1, but where the lower disc number is higher than 1, it does this.
