Whats the difference between the TF5800 and the TF5810?
The TF5810 is a new model, introduced in March 2008. It is very similar to the older TF5800 PVR but with a new casing, a larger hard drive and an HDMI port, which allows the picture to be upscaled and sent digitally to an HD Ready TV set. It also supports Freeview Playback from introduction, whereas older TF5800s require a firmware update. A more detailed comparison of the two is available here.
