Always burning in subtitles since 2.4 R11

Although I have not changed any settings since upgrading to 2.4 R11 I now have a problem with subtitles automatically burning into my conversions from Windows Media Center.

Any thoughts? I don’t do full logging, but I can turn it back on if that will help. Mostly, I’m looking to see if anyone is having this problem, if it’s a known issue, or not.

Like I said, I haven’t changed anything, but I’m getting different behavior now.
