Hmm.. ALLOW_MEDIUM_REMOVAL failed with timeout. To me it seems that your TSST dvdw doesn't like being poked continuously. I'm not sure how HAL is currently poling but it seems each poll involves opening and closing thus invoking whole media revalidation and medium removal disallow/allow switching. You're not the first one reporting similar problem. Can you report it to HAL people? I'd love to talk with them.

Thanks.
