At some time code locations, Pro Tools will not let you loop play because it says you are not on frame boundaries; even though the cursors were set with frame locations in the Transport window, and by definition, these should be frame boundaries.

The workaround is to use the cursor to make your selection, rather than manually entering time code locations.Seen in AVoption and AVoption XL 5.1.3
