If you play someone online, you can use the upload function to save it to your PS3 and then transfer it to your computer. Anyways, I'll try my best to answer your questions since the DJ soul arena is a ghost town. But this is all based on what I do, and I'm no expert by any means. If you want a more accurate answer, I would PM Donutman and maybe Party Wolf, since I've seen him put out some good DJ videos.
1. EWGF is good option depending on the wakeup attack as it's i14. Attacks add at least 15 frames to the WR attack, so EWGF should beat them and be chained to 3 more EWGF, or throw in a AS A9 BE for ringout. 46AA3B (LS) is a powerful option too for its combo ability. When in doubt (or slow like me), 4K works and combos on CH. Plus, 4K will pressure your opponent to move, leading to more EWGF and LS.
2. The two WR options I use is WR B and WR KK. WR B is a good punisher (and AS mixup) that launches and you can follow with a AS A9 (BE) or EWGF. WR KK doesn't combo well, but the first K hits grounded and the second K is safe. Maybe WR AB BE is a good punish since its i14 and +4 on block, but it needs a CH to combo. I would save my meter for something else, though.
3. If your opponent adapts to an oki EWGF, they'll start ukemi, which is when the fun begins (another EWGF, 4K, LS). Though, from what I practiced, the EWGF sometimes whiffs grounded opponents. For example, when I do 66B+G to EWGF, if I do the EWGF to early or late, it whiffs. I think its like 4K, which depends on angle and stuff to determine whether it hits or whiffs. 4K is also a good option for the reasons stated in answer one. A+B BE is also good if you got the meter. It has combo ability with 66K or 66 EWGF.
4. The only real deal DJ tech trap that I know of is EWGF. It's +6 on block.
5. 66K great way to close the gap between you and your opponent. DJ's biggest weakness is range. His number one goal is to get in range and stay in range. 66B is a quick mid, safe, rings out, wall splats, a good AS mixup. The only combo potential I've seen is near a wall. One of my favorites is 66B~W!~4K~46AAB~W!~3KBK8~FLY A+B for well over 100 damage. There are more combos however that take advantage of EWGF and CE. Another gap-closing move I kind of use is 33K and 33(K). They're tech jumps that give +6 and knocks down, respectively on hit.
I get so much salt from playing DJ (and only DJ, it baffles me). I agree, it's fun to watch. If you got any other questions, ask and I'll try my best to help.
