On one of my boxes/TV, I only receive the audio for FXHD, not the picture, how can this be fixed.
Both buckycat and mark_vse are correct in that the reason for this occurring is that FX Canada (HD) requires an MPEG4 capable hardware set top box.
Here's a document that may help provide further clarification: Guide to MPEG4 Channels and Digital Cable Boxes
The box is probably an older one that doesn't support mpeg 4. Unfortunately the only solution is a newer box that does.
To receive fxcanada, the hardware required is an mpeg4 set top box.
The behaviour you are seeing is because the box is not mpeg4 capable.
