I have issue like this.
Client said the video is not playing in ipad having him.
when i itested on ipadpeek.com , it works.
i had found your great tips to test ipad looks in safari using you defined above.
here also the videos are playing very well .
i changed the user agent sting which client have.( each time the user agent sting which request for video , i am storing in one notepad)
so i have client's ipad user agent sting. and i insert into safari browser and using your trick, it works... mean the videos are working.
so may be this is the issue with ipad or some configuration is needed to play the video in ipad???? may be client side device issue??
please advice and sorry for poor English....
Thanks in advance...
