Triax modulator problems


Novice Member
Hi all,

can anyone tell me why when I run a sky hd box through a triax modulator (mod103t) the picture is over a second out with the sound which is connected via phono leads into an amp which runs ceiling speakers. There is no issue when the sound is coming through the tv’s speakers and also the hdmi signal runs through a splitter into a balun which runs a separate tv/ amp and the sound on this is spot on. It seems as if the modulator processes the video signal too quickly!!??

if anyone could help I would be extremely grateful.

What audio codec on the Triax?
MP2 or AAC?
Whatever try the other to see if it helps.

Why not use the digital sound via HDMI and see if that is better? Though this will mean restricting the sky box output to stereo.
