I'm getting errors on multiple games trying to rip them.
I've tried
-Halo 3 (I get and error @ 140000 (somewhere there) and then get error @ 0 on the last of the two data bits)
-Oblivion (tells me that it isn't a DVD :S)
-Forza 3 (Error @ 0 also on the 2nd data bit)
This is a picture of me trying to rip Forza.

I'm not sure if I'm doing something wrong or not please let me know if i am

The steps I'm taking are as follows
1. Insert a disc (I'm using a DVD-R DL (not sure if it matters if its a - or a + when ripping) 8.5gb full)
2. Find magic number, save layout and edit it to have 3 dummy files first.
3. Stop disc.
4. Remove magnet take data disc out replace with game disc, replace magnet.
5. Spin disc, Dump.
