I'm not sure I follow exactly. However, the Mac TV did not use the same TV or Video card as the Performas. It was a proprietary combination card with an NTSC composite video and RF input.
The Performas and other Macs which would support it (see http://support.apple.com/kb/TA34375?viewlocale=en_US ), used a 2 part system for AV. It consisted of a TV (or TV/FM) tuner card with RF input, specific to the region sold, i.e. NTSC, SECAM, or PAL (with or without the companion FM tuner). The second part was a video input card with composite and S-Video connections, which universally accepts all three types of signals since the decoding is handled by the software in the computer. Apple's documentation is very clear, In order to receive television signals, the appropriate tuner card must be installed, i.e. NTSC, SECAM or PAL. You seem to indicate that the TV Tuner card included in your Performas were "universal" and could correctly tune any NTSC, SECAM, or PAL signal received. If that is the case, it would have been a more expensive version of the single format card which Apple documents in its English documents, sold exclusively in certain territories which might require such abilities. Based on this chart: http://upload.wikimedia.org/wikipedia/commons/0/0d/PAL-NTSC-SECAM.svg Brazil might be a prime candidate for such a card assuming there is a wide overlap of NTSC and PAL signals along the borders broadcasting in the same language. Certainly this is not the case in Europe, or Africa. Nevertheless, Apple does not document such a card, but they don't discount one either.
