Had this problem just now with my DCR-TRV460 Digital8. Stuck tape in, camera ate it and didn't fully eject (compartment slid out but did not open). Wouldn't open or slide back in after this.
Removed the battery and replaced, compartment slid back in and ate the tape a little more, but ejected fully, allowing me to remove the tape. Camera is fine, tape was bad.
