Eh? Are you trying to ask what Pokemon Hoso is? Well, I can answer that. Pokemon Hoso was a show in Japan that occasionally played re-runs (I believe) of old pokemon episodes, showcased clip episodes of pokemon, and also played special episodes. These special episodes included ones like "Slowking's Day" and I think the Mewtwo Returns special as well. After these it began to play episodes of the anime that centered around people other than Ash. Some were about Misty, or Professor Oak, Butch and Cassidy, Jessie and James, Richie, etc. Those are the episodes you have. I think there's around 20 or so of them. 4Kids dubbed them and gave them the title of "Pokemon Chronicles".
If anyone thinks I'm wrong on something don't hesitate to correct me. I'm a little fuzzy on what Hoso showed before the actual 'special episodes'.
As for subs of them, they're dubbed now. Just go download the dubbed versions. ^^ Though, if you really want subs... I wouldn't know where to go.
