Hi Jpourzand,
Sorry to hear you're experiencing visual issues with certain apps and channels and that you're keen on getting it resolved.
Are you still experiencing picture issues?
For the affected Virgin Media channels, what type of channels do you not get a picture? Ware they HD or Standard Definition?
Can you take a look at our service status checker just in case there is a known fault in your area?
Look forward to your reply,
Regards,
