I’m not terribly technically proficient, but googling “I/O Error ScsiStatus: 0x02” turns up some mentions of outdated drivers in the help forums. You could check to make sure your drive’s firmware is up to date.
Here’s a YouTube video to help with updating the drivers made specifically with imgburn in mind.
There is also mention of making sure your drive is free of dust, and making sure you got name brand Verbatim discs and not imitation ones.
Another thing to keep in mind if watching from your computer is an option: it is possible to watch the ISOs as if they had been burned, but without using a disc, by mounting it as a vitual drive. The last part of step 10 in the guide in the first post of this thread addresses this.
Also a good free Blu-ray player software to use either for burned discs or mounted ISOs is Leawo. It has worked for me when VLC would not. (It’s been about the only time I’ve found anything that VLC could not handle.)
I posted about it here.
