7 Day EPG

HI Iam new here so please bear with me.. I recently purchased a top of the range Free view box which also gets internet access and there is a forum for it .So folk on here might be saying what am I doing here.Well to honest the makers of the box (Netgem) will not say one way or the other if the I-player will be able to support a 7 Day EPG folk on there are pretty peed of with the lack of commitment from Netgem so I am asking any body with technical knowledge if the box will support the 7 Day guide.. it is Mheg 4 compliant and runs on the Linux (Embeded) OS
Will such a guide work or not..Thanks
