JoeKoz,
Welcome to DBSTalk! :welcome_s
If you have just the H20 HD receiver and no others, the only fee that would be $10 would be for what they call the "HD Package", which is certain channels in high-definition that are not part of their other packages. Those include channels like ESPNHD, ESPN2HD, HDNet, HDNet Movies and others. Check their web site for the HD package and what it includes. As noted below, I do not believe you are reuired to subscribe to this.
The only "lease fee" you would be paying is the $99 you already paid for the H20. If you have more than one receiver or DVR on your account, each additional receiver beyond the primary one is charged $4.99 a month, and on leased receivers it shows as a "lease fee", though it is really just a fee to mirror the programming on the additional boxes.
You've already paid the upfront fee for the receiver ($99) and it's your only receiver, so the additional $4.99 a month does NOT apply.
Quoting from the ordering page on D*s web site - "Offer for existing residential customers only and requires a two-year programming commitment to any TOTAL CHOICE® or DIRECTV PARA TODOS® package. Offer Details
The DIRECTV® HD Package ($9.99/mo.) contains ESPNHD, Discovery HD Theater, Universal HD, HDNet, TNT in HD and HDNet Movies. HD special events are also available. And the DIRECTV HD System makes all these channels available to you."
I take this to mean that the HD package is available and includes additional channels that the regular programming packages do not, however the only REQUIRED programming is Total Choice or better - it doesn't look to me like you are required to get the HD pack at all. So for you, other than the $99 you already paid, you are not required to pay for any additional other than what you are currently paying - as long as you are subscribing at least to Total Choice. And you need to maintain that level of programming for two years from the date you activate the H20.
If you are also getting your locals in SD from D* already, your HD locals (if available in your area) are included at no additional charge.
