I think you must have forgot the link.
As far as I know only pro models EX the GL-2 have line level inputs. You can always add the sound later, I'd wish whoever the best of luck trying to get decent results without it looking like a kung-foo movie (yes, sync issues). If you're recording the audio with an audio recorder, why sweat over very very minimal noise by utilizing the recorders headphone out? If you look at the input specs on typical vid camera mic inputs you'll realize that they aren't exactly the cleanest input, in many cases worse than the noise introduced by the headphone out on recording devices.
sorry - I meant the links that I put on the how-to page

You really only have to figure it out once to determine the clock differences between your JB3 and camera. I'm reasonably confident that the V3 (optical) > JB3 will sound better than passing analog thru the JB3 and into the cameras preamp/a>d.
Here's an idea on synching - if you record with the JB3 at 44.1, you're gonna need to resample to 48k for a dvd. The trick is to determine the right resampling rate (close to 48k but not 48k) that will synch them, and then set the header to 48k. Here's the thread
http://taperssection.com/index.php?topic=35629.0Having done it a few times now, I can tell you it works very well and the R8Brain freeware that I refer to does the job quite nicely if you don't want to play around in a wave editor. And after you've done it once you have your 'magic number' for synching the 2 recording devices.
