I have a Sony WEGA TV (precise model unknown, however it is silver) and whenever I burn a DVD myself that hasn't already been pre-encoded for VTS by someone else I get a problem.
You'll notice that the bottom subs are almost entirely cut off, while the top is left almost okay.
Now, it is worth noting that my tv has a "16:9 enhanced" mode, where it squashes the TV's resolution down to a mock widescreen. I end up having the subtitles, but it doesn't seem quite right. So, now I ask you - really really bad overscan, or encoding error? It's worth noting that I use avi2DVD.
