DVI was developed by the computer industry as an interface for LCD monitors (which are digital display devices). The standard includes provisions for analog data to pass through DVI (identified as DVI-I, where the second I stands for integrated I believe). As a result, there are some pins in the DVI connector that are reserved for analog data. The only way that a breakout cable would work with DVI devices is if the source provides analog data at the DVI connector. Mktheater's Momitsu is pretty unusual - almost all consumer electronics with DVI are digital only (DVI-D), so a breakout adapter would be completely useless.
