Picture is fine all channels are coming in. Its the audio delay. Since you brought it up, what exactly is the technical difference with X1.I am a retired cable tv engineer so do not hold back on a detailed explanation. Is each channel an IP based stream as opposed to a discrete Qam broadcast? If so, why would my Apple Tv services not have a lag in their audio also. X1 seems for me to be more like marketing hype , simply more of modern looking guide and navigator than a new or better technology. It seems to be less robust worse at error correction than the older Qam boxes. Also, should i simply insist on a trouble call, whcih will no doubt involve another box swap?
randy sorry I missed that tech question. x1 with STB is all QAM, lots of rumors about IP but nothing from comcast. The current conversion to mpeg4 from mpeg2 is apparently first step toward all the features mpeg4 suppports like control stream adding ability for all kind of meta data (ATMOS, AFD, others I haven't yet memorized). It appears from reading elsewhere mpeg4 also supports more security demanded by the MPA etc. and comcast appears to be upgrading/transitioning to DoCSiS 3.1 for the same reason. The local broadcast channels (again read elsewhere) are going to be in mpeg2 while others will be in mpeg4 for HD and mpeg2 for SD. based on that the same shows in SD and HD on the DVR wouild take up almost exactly the same amount of room. As you know the QAM has multi-channels in each QAM channel band.
Hope I covered the items you wanted.
