I'm having issues with my sons TiVo OTA and two mini set up. Both of the Minis freeze and stutter on any HD programming. Everything is connected by Ethernet and I have tested all the cabling and it tests fine. One Mini is a 9300 RF model and the other is a Mini Vox. I've moved things around and the problems exist regardless. Everything plays fine on the TiVo OTA it's just the minis. Initially I suspected network issues but that doesn't seem to be the case. Wondering about a hardware issue.
