and subtitles to dsmux (requires Gabest's Subtitle Source filter). Added an option to
disable error messages, the splitter will silently fail on invalid/unsupported files.

AVI files larger than 2GB, it is now included in the splitter package.
[OGM] Added support for a couple of other ancient versions of the format.

======================================================
NOW..... It's a Girl!! Congrats Blacksun!!
- 6. Known or Possible issues
======================================================
- Haali's splitter has been reported to not install on Windows 7. We are looking into the issue.
- CUDA does not handle interlacing at this time and the decoder will fall back to software decoding.
- Non-compliant H.264/AVC Motion Vectors are not supported. Some HD video's are using mastering/encoding with 'out of spec' encoders.
It is not really a bug.... but more of an FYI if you find such encodings.
To see or report any issues, visit our bugtracker.
