Hi,
I have had this problem also. Recently purchased this DVR from Maplins in the sale. Have 4 cameras running through it. I have no complaints with it except the software i VERY buggy!
I took the first DVR I had back to Maplins and exchanged it for this one, which was working perfectly until tonight when I logged in, then it crashed.
Also, states on box "works with Blackberry", it doesn't! Supplied CD did not contain software, spent hours hunting it down myself on the internet, then I cant get the damn software to work, it shows 1 frame, then goes black!
Let me know if you find anything that will help, will sure do the same if I come across anything!
Cheers
Rich
