I bought a TViX 6632N. After HDMI connection and configuration parameters of the Dolby Digital audio output digitally as recommended in the manual, I realized that there was no sound on the strings TF1HD, France and 2HD M6HD. No problem with ArteHD and SD channels. You must configure the analog audio output at all to get the sound but there was the sound in stereo. So I consulted in particular that of the official forums site Divico [...] In fact the TViX 6631N and 6632N TViX does not decode Dolby Digital French DTT HD channels (except Arte HD). The problem has long been known and begins to seriously aggravate the users. If I had known, I would not have purchased this model.
