I have come across several very nice quad core server boxes that I am going to fill up with hard drives and one will be used for streaming video back and forth to the TiVo. I have terabytes of TV shows that I recorded and converted to .avi for viewing on my PCs that I would like to be able to stream back to the TiVo. I also am looking for something that will automatically copy new shows from the TiVo on to the server. Since I am building my own server for this, what OS works best with TiVo (premiere)? I have read many articles claiming WHS works well with TiVo but I have found nothing saying it can stream video back to the TiVo or automatic backups. I was also looking at a linux server option, any particular version of linux work well with TiVo? I have seen similar threads, but the majority of them were not for home-built options, so I am looking to see if anyone has anything to share about TiVo with a home-built server! Thanks!
