That video is 50 mins long and the audio sounds like a robot from the fifties, so you are right--I am not going to watch it. I can only assume you believe Jesus did not rise on Sunday. I find that to be a minor point to worry about. The important thing is that he died and rose from the grave to save all those who believe on him. So it is not at all important that Jesus rose on Sunday, but the fact that He rose is.
Even so I believe you interpretation is wrong as scripture recorded in Acts 20:7, 1 and 1Corinthians 16:2 clearly identifies Sunday as the day they gathered called the Lord's day.
So you believe that Friday at sunset to Sunday morning before dawn is three days and three nights? It is obvious we graduated from different schools.
Acts 20:7 from the Diaglott...

From Bullingers...
Acts 20:7
first, &c. = first day of the sabbaths, i.e. the first day for reckoning the seven sabbaths to Pentecost. It depended upon the harvest (Deu_16:9), and was always from the morrow after the weekly sabbath when the wave sheaf was presented (Lev_23:15). In Joh_20:1 this was the fourth day after the Crucifixion, "the Lord's Passover. "Compare App-156. This was by Divine ordering. But in A.D. 57 it was twelve days after the week of unleavened bread, and therefore more than a fortnight later than in A.D. 29.
I Cor 16:1-2
1Co 16:1 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye.
1Co 16:2 Upon the first day of the week
let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
so what am I supposed to do, remove from the plate, take it home and lay it up in store? This is about foodstuffs being prepared and preserved for the starving saints in Judea, especially Jerusalem...
Act 11:27 And in these days came prophets from Jerusalem unto Antioch.
Act 11:28 And there stood up one of them named Agabus, and signified by the Spirit that there should be great dearth throughout all the world: which came to pass in the days of Claudius Caesar.
Act 11:29 Then the disciples, every man according to his ability, determined to send relief unto the brethren which dwelt in Judaea:

1Co 16:4 And if it be meet that I go also, they shall go with me.
2Co 9:1 For as touching the ministering to the saints, it is superfluous for me to write to you:
2Co 9:2 For I know the forwardness of your mind, for which I boast of you to them of Macedonia, that Achaia was ready a year ago; and your zeal hath provoked very many.
2Co 9:3 Yet have I sent the brethren, lest our boasting of you should be in vain in this behalf; that, as I said, ye may be ready:
2Co 9:4 Lest haply if they of Macedonia come with me, and find you unprepared, we (that we say not, ye) should be ashamed in this same confident boasting.
2Co 9:5 Therefore I thought it necessary to exhort the brethren, that they would go before unto you, and make up beforehand your bounty, whereof ye had notice before, that the same might be ready, as a matter of bounty, and not as of covetousness.
2Co 9:6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
2Co 9:7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
2Co 9:8 And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
2Co 9:9 (As it is written, He hath dispersed abroad; he hath given to the poor: his righteousness remaineth for ever.
2Co 9:10 Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness
2Co 9:11 Being enriched in every thing to all bountifulness, which causeth through us thanksgiving to God.
2Co 9:12 For the administration of this service not only supplieth the want of the saints, but is abundant also by many thanksgivings unto God;
2Co 9:13 Whiles by the experiment of this ministration they glorify God for your professed subjection unto the gospel of Christ, and for your liberal distribution unto them, and unto all men;
Paul and Barnabas took the stores to Jerusalem to give to the brethren there.
There are three scriptures taught to every young, hopeful graduate from seminary that supposedly justifies Sunday worship. You brought up two of them and didn't mention the third...
Rev 1:10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
None of the above refer to Sunday worship.
As far as which day Christ rose on being unimportant, you are wrong...
Mat 12:39 But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:
Mat 12:40 For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
Either He did exaclty what He said He would do, or He wasn't able to and therefore was not the Messiah.
