KB831937: This Hotfix corrects specific application compatibility issues with DirectX 9.0 changes in the DirectShow DV Decoder and Multiplexer
-
Changes made in DirectX 9.0 has the potential to affect two configurations:
1) Print to tape using a DVCPro device with a non-MS DV encoder may result in audio dropouts or complete loss of audio.
2) Decoding of a live or file-based DV stream with the PAL bit erroneously set in some frames may cause decoding to stutter or halt completely.
-
Modifications for these issues are as follows:
1) Alter DV Multiplexer to set SPEED field value in AAUX source pack to 1.0 when DV encoder does not set a valid value.
2) Change to buffer size checking in DV Decoder to accept non-standard assertion of the PAL bit.
Note: The English hotfix package (ENU) may be deployed on any language installation of the supported operating systems .
