Big Boar,
I found tons of videos for free on www.YOUTUBE.com. Just search whatever strikes your fancy, a particular detector, or, generalities, like hunting sidewalks..... http://www.youtube.com/results?search_query=detecting+sidewalks&aq=f
.....detecting yards.... http://www.youtube.com/results?search_query=detecting+yards&aq=f
detecting relics..... http://www.youtube.com/results?search_query=detecting+relics&aq=f
........ detecting coins ...... http://www.youtube.com/results?search_query=detecting+coins&aq=f
The search opportunities are endless. I found like a seven or so part series something like the complete guide to metal detecting. Unfortunately, it was in a foreign language, It was sort of like English, only spoken with a British accent.

It was very, very good. It is here, along with other guides... http://www.youtube.com/results?search_query=guide+to+metal+detecting&aq=f
What I did was to get a YOUTUBE downloader and convert software. I converted the "dot".FLV and other files from YouTube, to a format, usually "dot".mpg so that they will play on my DVD player and my larger screen TV. You can watch the files downloaded from YOUTUBE on your computer, but it is neat to see them on a larger screen TV. You can get the software by going to downloads.com and searching YOUTUBE. http://download.cnet.com/1770-20_4-0.html?query=you+tube&platformSelect=Windows&tag=srch&searchtype=downloads&filterName=platform%3DWindows&filter=platform%3DWindows
Each file will tell you if it is FREE, or, if it is shareware that must be purchased after a trial use. I really like PC UTILITIES, PC ADVISOR, and to a NOW, much lesser degree, PC Format and PC PLUS magazines. Especially, with PC UTILITIES, a British mag, available at stores like Barnes and Noble book sellers, they have TONS of free software inside on a DVD Disk. The disk is often glued onto the front of the magazine, just flip the pages and it should have a rather detailed listing of the software on the DVD. I haven't seen PC ADVISOR in a while but it used to be great on providing older full working programs of commerical software that were not trial, nor, demos but full programs. PC PLUS and PC FORMAT were my all time favorite Brit free commerical software mags, but they are both crap now, dealing mostly in demos, and games.
Take a look, the software is out there.
Years ago, I needed software to convert the WINDOWS MEDIA CENTER files that I recorded directly onto my computer from cable. Windows used their own proprietary format, something like DVR-MS,which you could NOT burn to DVD and play on your dvd player connected to your TV. http://www.google.com/#hl=en&sugexp=esqb,ratio&xhr=t&q=windows+media+center+convert&cp=27&qe=d2luZG93cyBtZWRpYSBjZW50ZXIgY29udmVy&qesig=EPUUJrlEztJvG4LF5MD0sQ&pkc=AFgZ2tkv0zfb8Nb3ouNWBMnxd1QJEYShETql2y2F9dDY5GuSc_pgC0lmsnvSn4EYQwRvnIUoXNK5kTV0TJ9Q2HViSCzepSxxjA&pf=p&sclient=psy&source=hp&aq=0&aqi=g4&aql=&oq=windows+media+center+conver&pbx=1&bav=on.2,or.r_gc.r_pw.&fp=4f5d99df8e6c9a1d&biw=1311&bih=539
Although, some of the YOUTUBE download programs at the www.downloads.com link above will convert YOUTUBE files automatically to usable files on your home DVD player, or, after the download, standalone VIDEO CONVERTERS for DVR-MS files and converters for FLV to MPEG, etc... are here... http://download.cnet.com/1770-20_4-0.html?query=convert+dvr-ms&platformSelect=Windows&tag=srch&searchtype=downloads&filterName=platform%3DWindows&filter=platform%3DWindows
I dowloaded a trial years ago, when it was about the only one converting DVR-MS files from Windows Media Center, and bought the paid version of DIGITAL MEDIA CONVERTER PRO... and have NEVER been sorry. It batch converts like a dream into a variety of formats that you choose, from a huge variety of formats. http://download.cnet.com/Digital-Media-Converter-Pro/3000-2194_4-10372005.html?tag=mncol;8
A bit stiff at $50 bucks but it does it all, flawlessly, including IPhone files. Again, by going to downloads dot com, or, in a PC Utilites mag, you will find free software that will probably handle most of your needs.
All the best,
