[Tvharmony.com] TVHarmony: Review: AverMedia UltraTV 1500MCE: From what I gather via Google, both SageTV and Microsoft MCE 2005 both support the AverMedia 1500MCE card, and I'm sure other software DVR products will likely either announce compatibility or add it in the near future. I would check with your favorite DVR package before purchase, but other AverMedia products are well supported so this one can't be far behind.
