Follow the directions in Channel Packaging and publishing, make sure you color scheme is compatible with the colors as described in that document, especially for the channel store - going out-of-bounds on the colors there will get you bounced. Make sure you spell check everything.
Avoid displaying web urls in your channel if at all possible, since they are meaningless on Roku.
Make sure nothing in your channel is confusing to users. If necessary, add some help text.
Don't use the word "LIVE" in your description if you don't actually have live content.
If they tell you to change something, change it.
Try to submit early in the week, Monday morning by 8am is optimal,
Wednesday afternoon is probably the latest you will get into the que depending on how busy they are.
You need to make an EPS file of your channel-store image, probably larger is better than small.
You will be sent a document to fill out after submission, fill it out and send it. Make a bookmark of the URL for the document.
