I'm looking for a small, lightweight DVD player for travel. One feature that it must have is the ability to output closed captioning (line 21 of NTSC video signal) to a TV. In most stores, this is impossible to test, since they have the small DVD players bolted down. I'm not really concerned with screen size, since I'd mostly use it to play thru hotel TVs. But I'd also occasionally use it on planes, so decent battery life would be nice. Obviously it needs to have A/V-out, and RF-out would be a useful feature. Any recommendations? Thanks!
