Why don't you try to use the AtomicParsley that comes with MCEBuddy:
CustomCommandPath = AtomicParsley\AtomicParsley.exe
CustomCommandParameters = %convertedfile% --overWrite --stik "TV Show" --TVShowName "TV Recordings"
CustomCommandHangPeriod=0
CustomCommandCritical=false
If that doesn't work, try to remove the --overWrite, it doesn't work sometimes.
