Technically Seeking Dispel cannot be countered by Jinx since Seeking Dispel prevents the enchantment from being revealed as soon as it is cast. Not that that's a big deal since it amounts to the same effect (except the player of Jinx saves one mana since they don't have to pay the reveal), but I'm just pointing it out.
Correct. I did a full breakdown a while back in another thread. It is listed below.
Enchantments
are
always played facedown, and remain hidden from your opponent until you choose to reveal them. You can decide that you would like to reveal the enchantment so that it has an effect on the game right away. You declare that you are is revealing it, flip it face up, and pays the reveal cost
When Can You Reveal?You can reveal an enchantment immediately after any action or event in the game:
• At the end of any Phase of the game round.
• Immediately after a creature is activated, before it chooses its actions for the turn
• Immediately after a creature completes its move action, but before it takes a quick action.
• At the end of any of the eight steps of an attack or three steps of casting a spell.
• You can reveal an enchantment immediately after it is cast, right after the Resolve Spell Step. When an enchantment is “resolved” it is placed face down as a hidden enchantment. Then, immediately after it has resolved, you may choose to reveal it at the end of that Step.
• You cannot interrupt an event to reveal an enchantment.
I also did a full breakdown for Seeking Dispel and Jinx interact
in this thread. Below I am listing the most important section of that thread.
Rather than this turning into a flame war lets look at what Bryan said.
Thanks for the compliment!
This is a really good question!
Okay, here is how this is resolved:
Casting a spell has 3 steps:
1) Cast Spell
2) Counter Spell
3) Resolve Spell
When Seeking Dispel is cast, as part of Step 1 it prevents the target enchantment from revealing.
When Step 2 is reached, the Jinx has already been locked down and cannot be revealed.
So, the Jinx is destroyed without being revealed.
The wording on these 2 spells conflict each other, because Jinx says "must". In cases like this where 2 equal events happen which conflict, we first default to the time sequence for resolution. In which case we default to the first event that occurred - the Seeking Dispel preventing the revealing.
In Mage Wars, everything happens in order, in sequence, and whenever possible we resolve conflicts in sequence, with later events not being able to change prior events.
In rare cases, when using time sequence does not work, we default to the Initiative order, and let the player with initiative decide (that makes it easy and fullproof! 
)
Hope this helps!

So lets brake it down.
-----------------------------------------------------------------------------------------------------------------------------------------
Step 1: Cast Spell
Announce that you are casting a spell and what the target will be.
You may only choose a target that matches the target requirements listed in the casting line.
Some spells will target a zone on the game board. Other spells will target
a single object.
Pay the cost(s) of the spell
Step 2: Counter Spell
Once the spell has been cast, your opponent has a chance to “counter” it. Normally, there is nothing your opponent can do, and the spell simply takes effect.
However, some spells and abilities, such as the Nullify enchantment, may allow him to counter your spell.
When a spell is countered it is discarded without effect, and you lose the mana spent and any action used to cast the spell (unless the spell or ability which counters says otherwise).
Step 3: Resolve Spell
At this point, the spell takes effect.
The spell type (e.g., conjuration) and the text on the spell card determine the effects of the spell. If you have cast an attack spell, you must now resolve the attack.
When a spell resolves, if you find that the target of the spell is no longer valid (has moved or changed), then the spell is countered.
-----------------------------------------------------------------------------------------------------------------------------------------
The trick is Seeking Dispel has text that applies on cast other text that applies on resolution. Jinx applies the "Must" reveal after the spell is cast. So Seeking Dispels "can not be revealed" text is already in effect.
I hope this helps
So If you reveal any enchant before you pass to your opponent they could not respond with Seeking Dispel
BUT once Seeking Dispel has been cast you can not reveal the targeted enchantment regardless of what the enchantment is. You can however reveal a different enchantment.
Reverse Magic and Nullify interact differently than Seeking Dispel so that would be in another post.
