You cannot press info twice to get information on the current programme; the EPG always lists every channel (ignoring favourites and TV only settings) and the EPG is extremely slow and unresponsive compared to previous versions. It also tends to freeze/crash more often. |

Vestel T816 based PVRs first went on sale in July 2007 after being in development since at least January 2007.
The T816 is a minor evolution of the T810 hardware, with double the amount of DRAM (64Mb) whilst sharing the same outer casing as the previous T810 model. The software was upgraded with Freeview Playback Group 1 compliancy on almost all models.
Sharp shipped a model that had fundamentally different software, which was known as Freeview Playback Group 2 back then. This software was never shipped with any other models and was never made available via OAD, probably for a good reason... Despite the advantages of the new features that the V6.x software had, these were somewhat outweighed by how sluggish and less stable it had become.
Eventually, I did manage to persuade Vestel to provide me with the V6.8 software so that people could at least try it if they wished.
