Does anyone know if the lil' HC20 included the AV cable? I think I lost mine. Is this something one can get at ~Best Buy? Does it output to svideo or RCA?

Is this the proprietary Sony cable?

As far as I know the cable is proprietary and not the standard A/V camcorder cable.

You might also try eBay...? Sometimes hard to find items pop up there. the B&H price looks decent though, and they sponsor this site.
The cable probably costs less than a dollar to make, so you may be able to snag it for less.

The B&H price is good so that's probably the best way to go. You can also buy parts directly from Sony. Go to the following link then enter your model number in the search field and you'll get a list of all the accessories available. But the same thing costs $20 from Sony...
