Can someone please tell me what each of the six channels are in Dolby 5.1?

I have video from a Sony Handycam DCR-SR100 that records Dolby Digital 5.1 audio in AC-3 format with MPEG-2 video.

I can tell for sure that CH6 is the subwoofer channel, but the others are unclear.
This is what I think they are from the audio:
CH1: L (Left)
CH2: R (Right)
CH3: LS (Left Surround)
CH4: RS (Right Surround)
CH5: C (Center)
CH6: LFE (Low Frequency Effects)

All literature I've found indicates L, C, R, LS, RS, LFE, but the audio files with some video I recorded indicate as above. I couldn't find a definitive answer by googling.
