I'd like to welcome you to the forums and say that I'm really sorry to hear that you're experiencing some freezing issues when watching your recordings, from past experience I know how annoying this can be.
I've done a few checks on your connection and can see an issue which will require a technician to call out and investigate further. So I've sent you a private message in order to get things moving with this.
Please look to the top left of this page where you'll see a red envelope icon. Click on this and you'll see my message.
