Generator Not Adding All Pages To Sitemap

[prodvideo]

First time creating sitemap worked without problems.  Submitted over 7000 pages to sitemap.  Second time I ran it, a couple of week later, generator only submitted 2400.  It scanned over 10,000 pages, but over looked many like this....

I've restored the old sitemap [ External links are visible to forum administrators only ]

The new one is [ External links are visible to forum administrators only ]

As you can see it's quite smaller.

Why didn't the new scan reveal all the pages on the site, plus all the new pages I added since the first crawl?  The new site map should have been bigger.

Please advise.

Below are a couple more samples of URLS that were submitted in the first sitemap that I created, but are excluded from the new sitemap.  I double checked robots.txt as well as noindex tags, and there's nothing that I can see that would prevent these from being indexed...
