@curiouscatholic23:
I second what Graham said; the uses you listed are fine and not a danger to your soul... just try not to watch too much network TV; the commercials are often as indecent (or even MORE) than many of the programs.
Remember that commercial TV is JUST that... TV stations are run as a BUSINESS, and that means the owners and programmers are out to make money. They will, and do, program whatever shows/attitudes/philosophies will attract the most viewers, and that obviously excludes most faithful Catholics. The programmers are not interested in encouraging your faith.
As for EWTN, please remember that they are TOTALLY Conciliar in their allegiances, they align themselves with known practitioners of Charismatic error and they have had their share of major scandals involving their hosts/personalities lately. I would not imagine that there is any danger to your soul in watching good, faithful movies on EWTN, but remember that their commercials and their in-house productions will be laced with Conciliar propaganda.
It's best to probably stick to DVDs or VHS where applicable; you can also subscribe to various online downloading services where you might be able to find some of the movies or shows you wish to see.
Search eBay and Amazon, as well as yard sales and estate sales... you never know what movies an older Catholic person might have had in their collection that will occasionally come up for sale.
May God bless you as you seek to order your home life according to His will.
Holy virgin saints of Heaven, teach us to guard our purity and sanctity for love of Christ.
O Mary, conceived without sin, pray for us who have recourse to thee.
Sacred Heart of Jesus, have mercy on us.
