You'll find torrents for STAR-431 here in the forum - MP4 and AVI.
But for MIDD-999 - there is only a RMVB torrent here (and I'm not a fan of RMVB) and dead links (except letitbit.net and shareflare.net which don't work for me).
I also found a torrent here, but it contains a different file instead. :tears:
