My dsl speed is 1.5mb, the best I can get from hulu is about a 100kb/s. I won't try two shows from the same site, but if I download from cbs and hulu each one will download at about 90kb/s. CBS downloads speeds can be higher if I download just one show from their site.
BTW, Have any of you been able to download South Park?
GetFLV just crashes every time I try it.
