Have been trying to record from a VHS tape to my DMR-HS2 using the composite connections (through AV3).

Played the tape through AV3 on the HS2 and it played in colour, but when I played it back from the HS2's HDD after recording, it was in black and white. Now, even when I try to play the tape as I did before in colour, it only plays in mono. Any ideas why...?
