The Mass that is generally seen on EWTN is, indeed, a mixture of Latin and English. It started as a Mass for the nuns and was, accordingly, somewhat different in nature from the ordinary Mass one would find in a parish church. However, their mixture of Latin and English is consistent with the missal. Liturgically it’s actually pretty good – although there were some issues that they faced with their bishop a year or so ago.
I remember the issue of Ad Orientum. Can you remember others?
If I recall correctly, the other dealt with the policy of not allowing communion in the hand. Since that is a decision made by the communicant it is not permissible to have such a policy. I noticed the last time I saw a Mass on EWTN that most still receive on the tongue, but a couple were receiving in the hand.
