Well what do u have and do u wish to change?
I have dish network ( 1 942 hd dvr and 3 811 hd recievers)
i recently tried out cablevision digital service becuase of the 18 free hd channels the hd was good but everything else sucked so im back with dish again.
now that dish has the 10 voom channels for 5 bucks its really the only way to go as far as i see it.
btw anyone who has directv hows the high def there?
