Garbled closed captions?

[Zeekar]

I'm trying to play a video stream I recorded off a US broadcast with closed captions visible, and they're terribly garbled. Characters are repeated in place of subsequent characters, etc... for instance, the text "OUT OF MY WAY" comes out as "OUOUT T OFOF M MY Y", and that's one of the more recognizable bits.

When I run CCExtractor on the same .MPG file, the captions come out ungarbled, so the problem isn't with the file. Any suggestions for figuring out what's wrong with VLC here?

I'm running 1.1.4 on Linux, specifically Ubuntu 10.10 64-bit...

Can you share the file?

Probably can't legally share the whole thing, as it's something I recorded off cable TV onto my DVR, but I could perhaps share a clip that exhibits the problem.

That would be nice.

Here's the first 30 seconds, which is enough to show a couple different captions.

The video was recorded on my TiVo, then converted to MPEG with tivodecode, then edited down to the above clip with ffmpeg. Captions show up fine on TiVo, and are decoded successfully from the mpeg (both full and clip) by CCExtractor, but VLC (on both Linux and Mac) garbles them (on both the full video and the clip).

Thanks.

If you change the speed of your VLC player to slower, captions will play out fine. It seems to be a bug within VLC that plays out captions too quickly, creating garbled(speedy gonzales) closed captioning.
