The following questions are for the WEC7 BSP for the DM3725.
Question #1 has been answered (fixed by setting I2S to 48kHz....TI driver was not used to control speed).
2. Support for WMV files is already existing as a software codec available out-of-the box in the catalog of Platform Builder 6. There is no existing hardware accelerated codec built using with the DVSDK.
3. You should be able to advertise one video codec to take a new input format, as long as the codec is actually capable of decoding that format. If this is the case then you can add a registry key specifying the GUID of the new format as a valid input for your codec, DirectShow may then use your codec as the decoder if this is the best match for the selected video source. This is done with the following registry key:

I've confirmed by disassembling their codecs that the answer to #3 is 'no' - TI just hardcoded a tiny set of allowed FOURCCs inside their codecs. NOP'ing out the comparisons does let them play additional files, for example the "DX50" FOURCC used by DivX 5.0 for MPEG4 content. However, this is not a usable workaround as it puts *no* limits on what the codecs attempt to play so they now attempt and fail to play completely incompatible formats. I do need limits, just broader than what TI used, so it looks like DVSDK CE source code will be necessary. How/Where can I get the source code for CE6 or WEC7?
TI never formally release the full DVSDK source with each BSP release. Instead only the binaries.
If you go back to some of the older CE6 BSP releases (I beleive they are still available on the TI site..you may have to search around) You can find the source.
