hey, I am having a very similar problem.
Here's the situation:
I have a series of tv shows on 3 dvds. last night, i used dvdshrink, made 2 iso's of the first disc, opted to go for the second i made, burned it this morning, no problems. I used dvd shirnk on the second 2 discs. I go to burn them, what do you know, the first disc, 33% into verifying it, it gives a I/O error, logical units time out. So I ignore it, go on to the third disc, burns fine, verifying, fails at 66%, same error.
excerpt from log:
W 02:01:01 Failed to read Sector 1481456 - Timeout on Logical Unit
W 02:01:02 Sector 1481456 maps to File: VIDEO_TS\VTS_01_3.VOB
E 02:01:53 Failed to read Sector 1481457 - No Seek Complete
E 02:01:53 Sector 1481457 maps to File: VIDEO_TS\VTS_01_3.VOB
E 02:01:53 Failed to Verify Sectors!

I 02:01:54 Average Verify Rate: 3,539 KB/s (2.6x) - Maximum Verify Rate: 13,464 KB/s (9.7x)
so now what do i do. I've done 20ish burns, the computers 5 months old, quirky, but works well
windows xp sp4 i believe.
any ideas?
lemme know if you need more info. I can get a lot, as the error seems extremely repeatable.
i should mention, i forced it to quit verifying, popped the disc out, put it back in, ran imgburn in verify mode, same thing, same place.
Thanks in advance

p.s.
other than this, I love ImgBurn
