problems seeking in ASF files

[deusdiabolus]

I'm not sure exactly what I did, but about a month ago, something I installed (either a codec pack or a media file player update) seems to have nullified my ability to skip through ASF/ASX files. The interesting thing is, I seem to have regained the ability to do this with Media Player Classic, but I still can't do it with BSPlayer (it just sits there). Any suggestions as to what to try? I believe I currently have the K-Lite Codec Pack installed....
