2. Q. Does the type of media I use matter?
A. YES: http://forums.afterdawn.com/thread_view.cfm/1/240341 If you're too lazy to read, use Taiyo Yuden, Verbatim, Ritek, Sony, TDK, Maxell, Sony or Phillips DVD-R's. Avoid Memorex, Staples, Imation, Dynex, Princo, Bulqpaq, etc.
CMC Magnetics is garbage. Need proof (Thanks to Alkohol):
http://forums.afterdawn.com/thread_view.cfm/1/262544 If you really want to do the PS2 backup thing right, pick up some Taiyo Yuden or Verbatim's. I only burn to TYG02, the 8x Taiyo Yuden DVD-R's. So far I've never had a lag, skip, freeze, or boot failure since I switched to Taiyo Yuden's. With results like that, why would I use anything else? The brand of media you use means very little.
The key determinant of media quality is the Media ID. For info on the Media ID, check the bottom of this thread.

49. Q. I'm rebuilding game X, I'm concerned it has dummy files. How do I identify the dummy files?
A. From Hursty: When you see the iso has dummy files.i.e 00DUMMY. 01DUMMY. GARBAGE, dummy, dummydata, dmydata, ETC, you need to get rid of them, by replacing them with a file. So on the desktop, right click the mouse, select "new" > text document and rename it as it appears in isobuster, then click enter. Then open the text document on the desktop, hit space once, then save, this will create a text document with 1 byte in it, Do this for all the dummy files you have, as some games have more than one.
