My system consists of: Sony tv - kdl-40v5100, Sony blu ray player, VIP722, and Onkyo Ht-s5200 home theater. HDMI from the vip722 to the tv with optical cable to onkyo for audio, HDMI from the blu ray to tv with optical for the audio. My problem: audio drops. If I run the audio through the tv direct from the vip722 the audio would have glitches, through the Onkyo the audio would actually drop for a second then come back. This audio problem was not network specific. This was not a problem with my tv. This was not a problem with my Onkyo. The problem is / was with my VIP722. I had to get three different VIP722 to get a good one. Now my audio seems fine so far. If that changes I will let you know. Wanted to let you all know that dish will send out these reconditioned VIP722's and it may take a while to get a good one so be persistant with dish. I had two older VIP722's, the ones with OTA antenna connection, this newer VIP722 does not have the OTA antenna connection. Is that the VIP722K then? Anyway, if you have the same problem, don't give up. Keep on dish network to get you a good receiver/dvr! It took me 2 months of hell to get my problem resolved..
