yeah MCE can do it to, but I believe it creates duplicate copies of the file, an SD version and an HD version and the one pointed to by MCE is the SD version, so I don't know if you open it separtely or manually overwrite...but timmmoore has done a lot of work on it
with Sage, it is more integrated but not really guaranteed to work (some peoples' combos of drivers, hardware, filters and decoders just doesn't seem to mesh), although some significant steps were made when sage started adding support natively for TS files which took a few steps out of the recording process
