I have had the Panny for about 5 months now and not had any dubbing problems until recently. I have now had 3 disks rejected (same disks as I have always used) when: 1. Dubbing in FR mode (twice - a programme just over 2 hours in length) 2. Dubbing in LP mode (a wedding video 3hrs 40 mins which I had copied from VHS to HDD). In all cases I got the same error message - failed check disk, and it appears in each case about 20 minutes seems to have been dubbed OK before the failure. Any suggestions?
