I have reported this problem and wanted to know if others are encountering this bug?
A work around is to remove the embedded YouTube video code from the web page and just put a link for visitor to view the video on YouTube. This is going to be inconvenient for me and I would prefer the problem be solved by CSE HTML Validator since there is something about their integrated browser that permitting their software to crash. The code when edited by another program works just fine with the embedded YouTube video in it.
