Updated last night's post with the snags I hit.

After playing with 6.2 for a very short while, aparently there is no way to configure or see your IP address from within the Tivo UI anymore. There are tools to set a static IP on your tivo from the command line, but aparently multi-room viewing (MRV) doesn't work anymore when you have a static IP. So, you have to monitor your router's local DHCP table to see what IP your tivo may have if you want to telnet, ftp, or extract shows. Another option is to have your router reserve a static IP for your Tivo's MAC address. My Linksys router doesn't allow this, so I am a bit screwed at this point. If the IP of my tivo boxes change, I will have to look at my router's DHCP table. Lame.

Other than that, the guide and menu speed alone is probably worth the upgrade. Also, my 6.2 box has no problem sharing shows with my other 4.0.1b boxes (soon to be upgraded).
