Sherlock Holmes is special, and needs to balance against HuVideo (Yuna & Gulliver Boy). The HuVideo ones read something like 10 sectors at a time, and magically don't incur a penalty for re-positioning. However, Sherlock Holmes reads something like 254 sectors, and does incur it. both also need to be within certain boundaries in terms of data read speed. These are the real balancing acts. Test them against each other, because a fix to one may require a tweak to the other (or break it)
