dephcon.com has various ecea enduros and hare scambles on DVD. About $24.95 each or you can buy a set of six for $100. There is also a video called "How to win an Enduro" one & two. If you do a search on motorcyclesuperstore.com for enduro videos there are a few out there.
Depchon's Enduro and HS races on DVD-R setup, so you well need to see if your system can use those. I contacted the owner of Depchon and he was very helpful and even took the time to look up my DVD player on the web for compatibility. The dvd's sound good too, most are about an hour of racing and deep woods views. Looking forward to getting one in the mail next week.
I'd like to find GNCC videos. It looks like Seals Communication Crop. has the video rights from the GNCC Racing Corp. in Morgantown, WV. and the races are only on OLN.
If any one has any info on GNCC videos, Please pass it on. Sorry to jump in on your post, but I'm looking too.
