Thanks for the quick response.
I forgot to mention, the YT video is playing normally when viewed on an actual android 4.0(ICS) device. however, the issue occurs on an actual Samsung galaxy S3 device and also no avail on most ICS android browsers on browserstack including JellyBean.
also ive tried your suggestion. ive Embedded a yt video on a plain html file and i got negative result on browserstack but totally working fine on actually android 4.0. this going nuts.
actually kindly take a look at this page, there's a video somewhere in the middle that doesnt play on android mobile jellybean
