I wish I new why it doesnt work. A wasted morning leaves exactly the same prblem: when I click on teh "icon" for either my blu-ray or HD-DVD start I get
"could not start program
COnfigSection [HDDVD]"
I had this problem too, 2 weeks ago.
The problem was, that my AV-Software (Norton AV 2009) has detected HDSTARTER.EXE as Trojan , so this exe was removed from folder.
After configuration AV2009, ignoring scan of pluginfolder has solved the problem.
