I watch bits of each DVD. I put pieces of paper in each case reminding me what match matches I've seen. I find I usually buy them for one or two matches so I watch them first and I'll watch te others when get round to them. I must have about 50 ROH DVDs with little bookmarks in them.
I have done that.. Well only on my family guy and simpsons DVD's..
I have the TNA christian cage dvd, it is alright...
