Problems with Humax PVR 9300 T

[amr2]

I have a Humax PVR 9300 T Freeview receiver and recorder linked up to my Panasonic TV.

Most of the time it functions well and does what it is supposed to do without any issue, but at other times it will stutter and the picture stalls for a second and then jumps forward. This happens when viewing through the tuner or through the recorded images.

I contacted Humax Support who agreed to replace the unit as it was still under warranty.

New box arrived and was installed but performed in exactly the same manner!

Spoke to Humax again and they suggested a software update (...not necessary as running the current spec) and a manual tune rather than the automatic tune used previously.

They provided me with the necessary info and I performed the deed, but with no improvement....

I am situated between two transmitters and the info provided by Humax was for the transmitter that my roof aerial was not tuned to. All my other TVs operate properly without any issue, although not using Humax products!

I contacted Humax and they provided me with the necessary manual tuning for the other transmitter and I have tuned it accordingly.

Everything works as it should and picture quality is fine, but still the picture stalls.......

Now what do I do?

Haven't had a chance to speak with Humax yet but would welcome any views from the PH experts.....

I have read that such problems are not unknown but is there a fix?

Any help much appreciated as I am sick of my DVD colection and normal TV is virtually unwatchable if the set is playing up!

Thanks.

Andrew.
