I found here a bit longer version of this video:
https://www.youtube.com/watch?v=dntzCBUiHog
There are even English subtitles and they say Alina speaks about HER dissatisfaction with the unclean combo.
The next thing is that your interpretation seems somewhat unstable to me because:
1. In your interpretation Alina speaks at first about herself (she is happy with the points she received, she says it's her season's best). Then she suddenly speaks about her coaches (?) being dissatisfied with her combo by refering to them only by using the word "they" (?), which woud be a bit disrespectful (she did not say anything about her coaches at least since the beginning of this video fragment). And then she again speaks about herself.
2. Few seconds later the reporter asks her "what did the coaches say after your performance?" Well, in your version she just said they didn't like her combo. So this question would seem kind of strange...
And I really hear her saying "ja nedovolna"
But I have good news. I've just run out of arguments, so I won't argue anymore.
