I think the 105 is a bit more choosy about media, than the 104.
I use the 104 and have had some success with the Bulkpaq Gen 4's, although I did get some coasters too.
I now use Datasafe Riteks and they are superb.
From what you say, if you managed to copy Spiderman ok, it doesn't sound like your method is wrong. I would seriously try another disk type.
Just a summary of my method, to check against :
Rip Movie Files with DVD Decryptor (vobs and IFO), using File mode.
Create Video_TS Directory, to store output files from
DVD2one
Run DVD2one, point it to Source Directory (ripped files)
Point it to Destination Directory (Video_TS )
Highlight the title to process
Select Audio & subtitles, if required.
and GO
Once complete, burn the VIDEO_TS folder, containing your files, with anempty AUDIO_TS folder to your DVDr
I use
Nero and all works well, but I gather version 5.5.10.0 has a bug, so if you try Nero, look for vers. 5.5.9.17 or below.
Good Luck m8
