Getting this device to work is pretty easy - which is good because the instructions are far from all encompassing. For TV viewing, only the top quality is worth using, and this is only just about average.
I initially used this with an external hard disk, and it was fine. I also bought a 16GB memory stick, and this was more of a problem - well actually it did not work. The device just refused to recognise it.
Pinnacle support subsequently admitted that it worked with some memory sticks, but not with others. To date I have not got any kind of hint as to which it which.
The weakness of Pinnacle is their customer support, and this was no exception. Initially they kept referring me to the same FAQ, which was irrelevant. Eventually they just said to use a different memory stick. Marvellous! It would not hurt to publish a list of memory stick suppliers that they recommend, then at least you'd know you were not wasting your money.
