Jerky QVC CR3?
 

Anyone else getting jerky pictures for QVC and ITV2 in the Northampton area?

Since they upgraded me to CR3 a few weeks ago QVC has been so jerky its been impossible for the wife to watch it! (Ah - is that a bad thing I hear you ask?!) ;-) It used to be fine til the upgrade. Anyway, I need to get it sorted for her so, if anyone has any tips or thoughts about what can be done then please let me know!

Thanks everyone!

They're on the same multiplex, can you press Page Up Page Down, Blue whilst watching either one of the channels, theres an AGC value amongst other info I'm looking for.

Woh! Proppinupthebar you are fast!


Ok.... AGC is at 487

Any other info you need?

Re: Jerky QVC CR3?
 

487? Are you sure?
Does it show values for pre and post RS errors?

That SNR (Signal to noise ratio) is pants. The pre RS errors are the number of errors your box is seeing before Reed Solomon Error correction is done. When the box is working it should be low (ideally 0), but the post error count is after the box has tried to correct errors, this should always be 0.

Its a call to CS I'm afraid, its probably due to poor levels getting to the box, but could be some interference. I'd be surprised if its only affecting one multiplex.

EDIT : Compare the values you get for a working channel and see the difference.
