Stagefright is a new media playback framework that was included in Android 2.2. Motorola chose to stick with the older framework, which causes some playback issues in some cases. A rooted user can enable the Stagefright framework, but it is not implemented fully in Motorola's ROM. It would make sense if Moto had this ready to go for the next OTA to 2.3, whenever that is.
Motorola's CEO announced that Moto devices would see 2.3 before any of the other competitors update their phones, so it's likely that they are testing an update for the D2G as we speak.
