In the duel between Yugi and Pegasus using the videotape, supposedly every Pegasus move was pre-recorded before the fight; during the first half of the duel, Pegasus used subliminal messaging by inserting images into some frames to make Yugi choose certain types of monsters, so Pegasus theoretically would play the correct card to defeat him every turn. However we also know this is a Shadow Game, so Pegasus could use supernatural effects instead of just manipulating Yugi using the frames or predict his moves due to his knowledge of the game and Yugi's strategies. So he (or his recording) can in theory use his Millennium Eye. According to the wiki, that was what happened:
Secretly Pegasus was using his Millennium Eye to read Yugi's mind.
However, the timing of Yugi's turn durations and Pegasus turn durations seems to be too synchronized to be a duel against a pre-recorded tape. On the other hand, if it's not a pre-recorded tape, then how Pegasus would be prepared to duel Yugi in the exact day and hour he watches it? It would be ridiculous to think about the long-haired businessman waiting all the time until Yugi put the tape in his video. But the wiki article suggests that the tape is more than a simple tape, allowing instant communication between the one in the tape:
Although it appeared to contain a prerecording, people on the tape were able to communicate with people watching as if they were present at the same time and location as them.
I can't find in the manga a definite clarification if the duel was against a pre-recorded Pegasus or the real Pegasus in the same time, being able to communicate due to his Millennium Item effects over the tape. Is there any official explanation, be it in the manga or another source, about what really happened in this duel?
