Hi, I have a Zenithink C91 running the 06/02 version of ICS from the Zenithink website. I have recently bought a 32gb card to store all my data on and have noticed that if I copy a video onto my sdcard when playing it I can't seek to later in the movie file. This happens with all the video playing software I try (MoboPlayer etc...). If I have the same file on a different sdcard (2gb) or on an attached usb flash drive I can seek without issue. I really want to work out whether this is an issue with the device not being able to use 32gb properly or whether it's a duff sdcard?? I know there is a later version of ICS available from Zenithink (11/02) but don't want to have to go through the faff of upgrading if I don't have to. Has anyone had similar issues or help??
