connect MBP to 8 TV's, problem with weak signal

[catbo1]

For a low budget theatre-art project
I need to connect my MBP (2.3GHz,10.6.8) to 8 old TV's.
I already have a converter ( company LIGAWO) that translates the signal from the mDP to VGA into analog video signal (cinch).
However the signal is not very strong. Connecting more than 3 TV's destroys the image quality too much.
Any advice? Are there suitable signal enhancers? Or is the initial signal already not strong enough?

Are there videocards for MBP available, that I might be able to use instead of the converter?

You either need to get some video amplifiers in there, or an amplified splitter.
You can also get some external USB video 'cards' that can drive up to 2 monitors each, but that may compromise performance depending what is being displayed.

Not an endorsement of the products below, but a place to start. Make sure that a splitter or switch is amplified, not just a splitter.
