Which Hauppauge card you get depends a little on what you want to do with the Mythtv system. My first mythtv box has a PVR-350 and a PVR-250MCE. I am using the PVR-350 output to the TV which works great for what I am using it for. The PVR-250 is essentially a PVR-350 but does not have the TV output or the remote control input. I use it as just another encoder card for recording shows. The PVR-350 comes with a remote control and provides Svideo and composite outputs. The caveat is that the output is good for things you record (the PVR-350 has a hardware decoder for mpeg2) but apparently getting a DVD to play using the PVR-350 output is not possible. If you want the mythtv box to be able to play DVDs apparently you are better off using a standard video card output to the TV. This means you will need more CPU. And if you go that route the PVR-350 does not make as much sense. I am not familiar with the PVR-150. However the PVR-500 is interesting as it has two tuners on the one card. I have found that having at least two tuners is required, otherwise there are many conflicts in scheduling. Two tuners eliminate most of the conflicts. Three tuners would be optimum, there should be very few conflicts if any with three tuners. The TV output from the PVR-350 replicates the input signal so well that I doubt that I could tell the difference between a live broadcast from the cable company and what is being played back from the mythtv box. In the next few months I plan on building a cheaper cooler quieter frontend box and may opt for using a video card output so I can get the DVD playback working. I also like the live tv listings better over the video card. With the PVR-350 the tv listings overlay the entire picture. When I was testing it seems that the output to the monitor put the current channel in a small box in the upper right corner and provided the listings below that. Much easier to view. So if you are not going to use the PVR-350 output you may be better off getting a PVR-250 and some other remote control setup. Not sure if there is much documentation describing these trade offs or not. I found out during the build of my first box. -- Scot L. Harris [EMAIL PROTECTED] Let us live!!! Let us love!!!
