My issues have been resolved. I used an old 256mb SD card instead of my 2gb Sandisk ultra card, I reformatted it to FAT 16 32k clusters. I then re-formatted my Hard drive to FAT32 32k clusters. Finally, when prompted in Modmii I went for install 72 instead of 75.
Unfortunately, because I changed various things all at once I cannot pin point the issues - if anyone gets a similar problem whilst running games (any with video cut scenes like tintin or the last story) then I would first go for the 72 install and see if that works. If not try a smaller SD card. If all else fails reformat the drive with the aforementioned fat 32 formatting tool in the tutorial.
Oh and don't forget to include the cios v14 when asked. I can confirm that v14 works alongside the above config.
Thanks to Highlander for the help, it's very much appreciated!
