BS4 does not see new videos, how to fix?

Question

Python

When a video appears on the channel I need, bs4 does not see it for some reason. Here is the code

def parseYoutubeChanel(channelurl):
    urlPage = urlopen(channelurl)
    xmlData = urlPage.read().decode('utf-8')
    new_video = BeautifulSoup(xmlData, 'lxml')
    for lnk in new_video.findAll('a', href=True):
        linkspage = lnk['href']
        startLink = linkspage[:6]
        if startLink == '/watch':
            newLink = 'http://youtube.com' + linkspage
            listvideoUrlLink.append(newLink)

Runs every 10 seconds.
