An unmodded wii cannot read a DVD-R and this has nothing to do with it. Period.
A modded wii can read DVD-Rs but IOS restricts you to game format DVDs (signed and encrypted). The UnencryptedRead patch disables this restriction, which means that you can read standard format DVDs and DVD-Rs (movies, normal ISO9660 filesystems, etc). If you have a modchip.
What controls sector reads, then? D2x?
There has to be some software intervention somewhere along the line... these games aren't exactly streamed sequentially, like movies.
