comcast seems to suck

i was using sbc-yahoo dsl and didn't have any problems with it. i switched to comcast cable yesterday and immediatley i'm having problems with uploading. EVERY upload has "transfer interrupted" and not ONE upload has gone through successfully since i've used comcast. i read an article about how comcast was choking p2ps and i guess i'm being a victim of this. i've read another thread on here with someone else having the same problem (also using comcast btw). how many people are having this problem? has anyone figured out a workaround? if comcast is successful with this, they will effectively kill p2p...
