Hi there !
I have another issue here with Bitdefender preventing H.264 videos to be played in Internet Explorer 9.
Here is the situation.
I have at Home a Synology NAS server which has a web application called "Surveillance station". Surveillance station is connecting and recording events from an IP camera I have at home.
For events recorded in MJPEG, or MJPEG live view in Surveillance station, the videos are correctly displayed.
For events recorded in H.264, or H.264 live view in Surveillance station, the videos are not displayed (black screen in surveillance station, instead of playing the video).
I have un-installed Bitdefender, and that is working again.
I have re-installed Bitdefender, and that is not working anymore ... so issue is really co,ing from Bitdefender blocking the "flow".
Can you please investigate the issue; let me know if you need further details, etc ... ?
Many Thanks !
