Your Standalone show's it will not play "+R's" which is the media you are using. The BookType is a setting that is used to change the type of media from +R to DVD-Rom which will make the media more compatible(-R, +R and DVD-Rom or booktypes).
-R's have a highier compatiblity list then +R's but with bit-setting you will have a more compatible list, you can only change +R's to DVD-Rom and not -R's
Most drives that support the bitsetting, come with some kind of software utillity that allows you to use this option, DVD-burning programs such Nero have an option that allows you to bitset to DVD-ROM on drives that support it, I am not sure about your drive, I will do some research and see what I come up with.
As for the 2hour burn, that is a long time, check your DMA settings to make sure you have "Transfer mode" set to "Ultra DMA Mode", unless you are talking about the entire process took 2 hours and if so what is your system specs?
