I think Windows Media Center is probably your best bet for the OS and DVR SW, but connecting to a component TV will cause some complications. Finding a modern GPU that does that will be difficult, especially considering the Blu-ray (HDCP) requirement.
While it is possible to do that, it’s always been a bit of a challenge to use analog outs from a HTPC. If you absolutely must use that TV, we can find something that should work, but it will be more expensive and less capable than an all digital system.
