Try not to lump to many LiveTV and InternetTV channels together in one block... This will slow down channel surfing since each channel change will require reaching an external feed.

Does this also apply to viewing the guide? Well, sort of answering my own Q, yes it does. Is this expected behavior? I would really like my internet channels to be ch 200-250. So am I out of luck?

Do most ppl have random internet channels lumped together with local content? Seems kind of silly, but I guess theres no choice, ex:
Friends TV
Seinfeld TV
NatGeo Youtube channel
Community TV
Modern Family TV

That warning is more like a general rule of thumb. If your using reliable sources it won't matter.

Reliable source = those in the community database? That's what my internet channels are made of, youtube channels and rss feeds. but it still locks up when my guide gets to the 200 channels. Actually when I page down from ch 1, I can get to 203, I cant go any lower, or if I do, it take 10+ seconds to load the next set of channels in the guide.

Heres my xbmc log, hope it also includes info from PTL that you need:
