First I want to say thank you to all who have taken the time to answer questions. It is greatly appreciated.
We managed to get one 'test' video uploaded over the weekend. Everything seemed to have gone ok. Now tonight when we try, the audio doesn't sync with the video (very delayed) and the video keeps freezing up when we try and play it back.We cleaned up the hardrive and removed things we didn't need in case it was a memory issue, but still no luck,

We are using a webcam. Does this sound like an issue we can fix somehow with the Movie maker? I am really afraid that it might be our not-so-great computer and then we are really out of luck. I invested in a webcam for this, but investing in a new computer isn't possible.

Does anyone have any thoughts or advice?
