Miglia needs to fix their other products before foisting yet another DVR solution, since their other ones hardly work!
My AlchemyTV card conflicts with iChat and I have to reinstall the software for it all the time, and even then, AlchemyTV is slower than hell, and it's been over a year since I bought the kit.
I hope ElGato's support of the ATI TV Wonder USB 2.0 unit is good, because that looks to be a good option. Unfortunately, no reviews yet.
