After many years of being a loyal Windows Media Center user, I've finally had enough of the bad EPG data, irritating configuration errors, Windows updates and overall upkeep aside from the fact that Microsoft has abandoned any further development to WMC. That said, I've decided to take the plunge with two Premiere XL4's and lifetime service and am waiting to receive them. I'm confident I'll enjoy my TiVo experience, however there are a few things I think I'll miss and hope TiVo will add these obvious omissions in the near future... With the advent of whole home DVR service, these seem like no-brainers: Dynamic tuner pooling (with my HTPC, I could easily add additional tuner cards and they would work together and be available for recording or to extenders on demand) A unified experience which pools all recorded TV, Season Passes, scheduled recordings, etc. from multiple TiVo's into one place instead of having to hunt for which TiVo contains what I'm looking for. Case in point, I'm not sure how I should break up and allocate scheduled recordings between the two units since they can't share tuners between each other to reduce scheduling conflicts. This could potentially overwhelm one, while the other is sitting idle - seems like a huge waist of resources... In my opinion, these improvements would make for a much more robust whole home DVR experience.
