Thanks Leo, The most inconvenient issue is the fact some videos no longer play under Opera so I guess this is the issue to be resolved first.

I have a problem in the last 2 days where most IMDb videos are returingin an error indicating they are not supported by my browser?

Thanks for the replies! Much appreciated.
I have just retried Thaivisa site today and all is back to normal. I have no idea why as I have not changed any settings.
The other 2 issues I reported are also OK today??? I didi report the issue to Thaivisa support maybe they did something. The issue regarding video media playing problems on some sites is also resolve but that's nothing to do with Thaivisa?

I just retried Dailymotion and Imdb site and videos from both sites are now working as expected albiet a little slower to load? No idea why as I have not changed any configs on my end. Obviously something has changed but no idea what. BTW: I do not have the Use (video) hardware acceleration setting on.

Yes, along with the Thaivisa site icon the social media icons on the top right are all sized up to each take my entire screen view.

It has only been happening for a week or 2 for me and I am now noticing other sites such as "Dailymotion" not playing their video media while Youtube seems to be fine. I did not download any new Extensions about 2 weeks ago. I have cleared history and caches etc in the past 2 weeks so not sure if that could contribute somehow?

I've posted 2 other issues that have also surfaced at the same time in relation to Adblocker treatment not working properly for one site along with the sites header banner. At least in timeframe it appears these are somehow related??

Description: This is working fine on Chrome and was working until 2 days ago for Opera but now the Social media icons such as FB, Twitter, Youtube etc are all supersized each one to the height and width of my display including the Thai visa icon.

To Reproduce just go to the http://www.thaivisa.com/forum/ The result is self evident.....for me at least.

Actual result: Supersized icons from the banner header being listed separately down the display page before gewtting to the other content which is shown as normal.

Expected result: A "short"Page Header Banner with small Social Media and site icons.

Version of Opera: 43

Go to http://www.imdb.com/
Click on any of the "Trailers" previews shown at the top of the page.

All will run as normal under Chrome and were running under Opera up until 2 days ago. Now very few run. The pages seem to finish loading but nothing is displayed except a blank black page?

Expected result: The video trailer for the selected short should play.

OS: Windows 7
