I don't think so only one subframe is dedicated/allocated to one particular MBSFN Area. Per TTI one transport block would be send and one transport block corresponds to one MAC PDU. If you look MAC PDU structure carefully then you can realize more than one MAC control element can be included into one MAC PDU.

Each MAC control element corresponds to one MCH scheduling information (MSI). And in turn, one MCH is multiplex of one MCCH and multiple MTCH.

Please correct me if my understanding is wrong.

LTE: How many TV channels can be broadcasted in one MBSFN area ?

I have very limited insight in mutlimedia multicast/broadcast services. An article says one LTE cell can have maximum of 8 MCCH channels and each MCCH configuration corresponds to configuration of one MBSFN area.
If this is correct then it concludes that one LTE cell can be part of max 8 MBSFN areas.

Each MBSFN area can be used to broadcast multiple multicast/broadcast services.
Now I want to how many TV channels (a kind of broadcast/multicast service) can be broadcasted ?
One related query is how an UE come know about the channels such as DD news, ESPN etc are being broadcasted in cell ?

LTE: Is it necessary all the cells belong to same MBSFN area should have same amount multicast/broadcast resources ?

Within the LTE network, different eNodeBs can be deployed with the different bandwidth configuration. Few eNodeBs may be deployed with 10 MHz and few with the 20 MHz. Now I have two questions here.
1. Is it necessary all the cells should have same bandwidth deployment ? If answer is yes then ignore the second question.
2. If cells of the same MBSFN area can have different deployment bandwidth then they would have different amount of multicast resources and what if when a cell exhaust with the allocated MBMS radio resources ? What corrective action MCE should take in this case when few cells of a MBSFN area does not enough room to accommodate new services and other set of cells within the same MBSFN area can serve ?

An eNodeB can be part of maximum 8 MBSFN areas only, why ?

While reading specification, I came to know that an eNodeB can be part of max 8 MBSFN area. I am not able to understand from where this number '8' derives ?
