Juttering on new discs. Could it be the player?

[Groge511]

For a while now I've been experiencing juttering picture on brand new blu-rays. I've taken them out and given them a clean (even though they are immaculate) but it doesn't seem to help.
The problem doesn't always occur in the exact same spot but it is usually within a minute or two of the original issue.

I'm finding it hard to believe that it can be the discs.

I have a Panasonic SC-BTT190 and it's about 2 years old.
It's firmware is up to date.
It is used every day, could it be worn?

Could it be the HDMI cable? It's a pretty standard cable and it's a lot older than my player as I used it with my previous one.

Are there various settings I should check within my TV or players menu?

My TV is an LG 37LE5300

Any help/advice would be much appreciated as I'm getting so worked up about it, it's trying me mental.

EDIT: Just tried one if the discs on a different player and it works fine. Gonna try out that HDMI cable later and see if that makes a difference. Quite worried it's the player
It would be better if it were just the discs

EDIT: Tried a different HDMI and no difference. Definitely the player so im guessing it could be a dirty/dusty laser lens.
Bought a cleaning disc so hope it does the trick

EDIT: Tried the disc. Didn't do a thing.
