Let me write this right up front -- I love Opera 37.

Having noted that, I'm having a problem understanding why Opera 37 fails to run videos on The Weather Channel (www.weather.com), but Vivaldi plays them without any problems. Likewise, if you go to xfinity (comcast.net) and try and view television shows and things of that nature, again, Opera 37 fails to view them but Vivaldi will play them with ease.

Question -- what does Vivaldi have that Opera 37 does not? When viewing videos, what is different between the two that causes success or failure of such viewing.

While using Opera 37 since its release, I've noted some changes.

When I used Opera 36, I was able to run four or five tabs simultaneously without any hiccups; mind you, I'm referring to tabs that were running videos, while another tab was utilizing the cam and microphone without any issues.

Last night, I had the opportunity to try out the same scenario with Opera 37, and the experience was degraded: videos came to a crawl while the cam sputtered on several occasions. The laptop and memory were the same, but the experience was lackluster. It's possible some optimization is required.

Continuing my thought with the Settings/Websites/Plugins selection, it seems that there are a few sites that if you have selected Click to Play,that the videos cannot be selected to play -- they are grayed out; this is why I was unable to play videos on www.nbc.com -- they weren't selectable. The http://videos.hgtv.com was another site I couldn't select unless managed as an exception to the Click to Play rule.

Okay, this is what I've discovered.

Under Settings/Websites/Plugins, I have selected Click to Play; I don't like videos to automatically play when I visit sites. If I manage www.nbc.com as an exception, the videos will play on this site even if ad-block is turned on.

I thought I would share what I'd discovered.

The site is www.nbc.com.

Using Opera 37 with the Ad-Blocker turned off, this web site will not play videos. The videos on www.hgtv.com will not play either. What is interesting is that Vivaldi 1.1 will play these videos, on the same computer, without a hitch.

I'm testing Opera 37, and I've noticed that The Weather Channel videos DO NOT work there as well. This is something that really needs to be resolved. The Weather Channel is a popular web site and its videos need to work.

Just a small issue here. I can view videos from any website other than The Weather Channel. Although I have Adblock Plus, I have the The Weather Channel website disabled in Adblock Plus. Still, I'm not able to view videos on their site. Anyone have any suggestions that can resolve this issue?

Note: I have the latest Flash installed.
