Step 1: Acquire Ded 2.5 DVD5 versions from website of choice (if you don't know how to torrent, download something like qbittorrent, then download the torrent file). We're not going to tell you the exact site to get it from because that is considered piracy. They are, however, extremely easy to find if you Google them.

Step 2: Use imgburn to burn the files (or ISO) to these discs: http://www.amazon.com/Verbatim-Branded-Recordable-25-Disc-95033/dp/B0003QIXBY/ref=sr_1_1?ie=UTF8&qid=1439409517&sr=8-1&keywords=Verbatim+4.7+GB+up+to+16x+Branded+Recordable+Disc+DVD%2BR+25-Disc+Spindle+95033

Step 3: Insert DVD into player and enjoy!
