To; dethnitebob,
Sorry for not posting sooner. It would have saved you having to reply.
I did solve the issue. But do want to point out that this was happening with no DLC or custom content. All I had merged into the patch were texture files.
What I did to solve issue.
1) Took patched folder and moved to merged folder in root DAI folder.
2) Had a clean updated zipped patch folder on ext. drive. Unpacked it to DAI update folder.
3) Open MTF file in notepad and changed version to 10.
4) Launched DAI and loaded saved game. When I got to point where it had been freezing. It froze again. This is with NO mods installed. Just a clean updated patch.
5) Based on all the reading I've done pertaining to this, I relaunched the game, loaded the save. But this time before entering the ballroom, I removed all weapons and armor from Inquisitor and companions, then put formal wear back on entire party. Then went into ballroom.
The scene play out completely, no freeze. All the way to Skyhold.
My conclusion: Must be wearing your formal wear before cut scene begins. Conclusion based on fact that I was running a clean updated patch. Nothing added, no mods, and it still froze. But with same clean patch and formal wear it worked fine. The only difference with wearing armor or wearing formal wear.
If others are having this issue even after trying the other suggestions here, then try this. Hopefully it helps. Thank you dethnitebob for your prompt reply.
Problem solved, now on to kill the next bug.
