"Though I saw a review of the AA daytime flight that said there was no seat back entertainment"
That's correct: AA's 767-300's have drop-down video screens, and about a dozen channels of audio entertainment, but no seat-back monitors. However, getting an MCE seat should make for a more comfortable trip than flying in Economy on BA.
