I think the OP has been slightly misunderstood, but appreciate it's because of the way he worded the question. Equally, it may be me misunderstanding and his question has already been answered.
In saying that, I read it as more of a question relating to seperate videos when the handling of a mechanic has to be markedly different. As an example, Aliena's video for Halfus Wyrmbreaker on heroic is practically useless to a 10 man raid; it talks about stacking tanks and using multiple Discipline priests to heal through the enormous amount of raid damage, neither of which is possible for a 10 man raid. I appreciate the mechanics of that fight have altered since then to accommodate 10 man groups, but the original video didn't help at all. Another example is Papapaint's heroic Chimaeron video - on 10 man, you simply cannot stand in one group and finish him off in the final phase with only 10 people, unless you have extraordinarily strong DPS (which most groups won't). It also comments on stacking raid cooldowns, another option that simply isn't open to 10 man raids without multiple classes and/or specs. In fact, in most cases, they'll be missing things.
The "mechanic" may be the same for each encounter, but you cannot handle it in the same fashion and I think the OP is requesting videos that deal with the same mechanics, but require vastly different solutions due to raid composition.
I totally understand that covering every eventuality would make videos last for three days at least, but people don't log onto TankSpot and watch the videos to learn what mechanics are in a fight; they watch the videos to learn how to deal with them. Perhaps addendums that highlight specific tactical variations? For those wondering what I mean, Lore's video of using a Protection paladin for the heroic version of Northrend Beasts (an age ago now x_X) should clarify what I mean.
It's no coincidence that pretty much every TankSpot heroic video is dealt with on 25 man, as the 10 man variant is typically far harder because Blizzard bungled the balancing act.
