On my setup I can normally hit the "eject" button on the DVD drive after it has locked up between the burn and verify state, and that normally returns the system to normal (of course it can't verify then).

I'm going to test these DMA settings tonight (/dev/hdb is my DVD):
1: hdparm -d 1 /dev/hdb
2: Adding these lines to /etc/hdparm.conf:
/dev/hdb {
       dma = on
       defect_mana = on
       lookahead = on
       cd_speed = 68
       write_cache = on
}

/dev/scd0 {
        dma = on
        defect_mana = on
        lookahead = on
        cd_speed = 68
        write_cache = on
}
