Describing the integration of VDR into LinuxMCE as more seamless is interesting. There are WAY more integration hooks of MythTV into LinuxMCE than for VDR, and this comes from a user who IS using VDR with LinuxMCE. At the moment there is nothing in LinuxMCE that supports analog in with VDR, however, feel free to experiment with it. http://www.vdr-wiki.de/
is a great start - a good search term is pvrinput.
