The AVI files created with Adobe Premiere 2.0 and the XENA HS cards are not compatible with any other program except After effects 7.0. Adobe did not make available a general windows codec for reading these files. They used the fourc code of UYVY which corresponds to a microsoft implimentation of YUV, but did not follow there format.
Great Job Adobe!! add this to your failure to include capture of imbeded audio over the SDI and you have done the best slop job of implimentation I have ever seen.
