Apologies if these anomalies have been documented here (or anywhere) on the Aug 2013 v3 firmware. I've only used this box for cable:
The Iview splash screen changes from yellow to white (so what?).
The "antenna loop through" function no longer works (somewhat moot unless you wish to "cascade" units that would have to stay on at all times}. Reverting back to the older v7 firmware restores this function. Modulating on Ch3/4 continues to work normally.
Scanning qam channels with v3 now removes all channels without a virtual channel in the Psip TVCT table. This is unfortunate, because some cable companies strip all of them, mine strips some of them. The older v7 software will put these in the list, but one must manually remove the scrambled channels. A full or manual scan under v3 firmware will NOT find any QAM channel that does not have a virtual channel listed in its TVCT. This would explain why some users get no channels at all after the new firmware is applied.
It would seem that the "improved QAM tuning" mentioned on the firmware site is based on the fact that only cable channels with a virtual channel number assigned are allowed to be decoded, and that all others are considered scrambled or irrelevant. IMO This would hardly be the case. To get those channels that do not have a virtual channel number in the Psip, one must revert back to the earlier v7 and do a complete scan, or a manual scan if you know where they exist. Then upgrade to v3 firmware, without doing a factory reset. By upgrading the firmware, this causes the initial setup to occur that requires a channel scan. One must use the "skip" button to get through each and every channel as it progresses through the scan. Additionally, several of the menu settings (country, air/cable, time zone, etc.} revert to their default setting.
Speaking of time, my cable company (Comcast) seems to think that their headquarters in
Denver CO is where GMT begins, so I must use manual, and select GMT+2. For those who do get a correct time from their cable company that is offset by an hour, if you are on the east coast and select "Canada" for your country of choice, you could use the "Atlantic time zone" setting to get the correct time. This is generic over v3/v7.
Tuning with the remote will now call up channels that have the TVCT present with just the first two digits (no need to enter -1). For instance, Channel 11-1 can be called up with the remote with 11 and OK. For those channels without a TVCT, you must plug in the entire channel number along with the subchannel number - ie 80-27, or it will show "invalid channel number".
Considering that cable companies move their channel allocations around all the time requiring a rescan, and might occasionally add a channel (free Showtime for a weekend, etc.), this procedure to re-obtain clear channels would be a PITA whenever this happens on a cable system. Perhaps the next firmware version (or the new STBII) can address this.
If more memory is required, the games can certainly be dumped... But I, like some others here think the display should be kept.
