0Unsolved: Decoding interlaced vc1 in Media Center x64

Whilst my MediaPC setup can decode just about everything thrown at it, I have had prob­lems decod­ing inter­laced VC1 con­tent. The prob­lem is caused by the fail­ure of ffm­peg to sup­port inter­laced vc1. Whilst there are oth­er codecs (উদাঃ. cyber­link or arc­soft) these are cur­rently not avail­able as x64. Cyber­link do have an x64 codec for h.264 and mpeg2, but I haven’t been able to get it to work with VC1 con­tent. Hope­fully ffm­peg will fix inter­laced vc1 sup­port soon, but as its been on the to do list for over 2 years I’m not hold­ing my breath
