A proper fix to the issue of Topfield PVRs not allocating enough memory to process the IceTV guide data needs updated firmware for the affected PVR models.
But with Topfield Australia Liquidated and Topfield International struggling to survive any new firmware updates look extremely unlikely. Topfield International held an Extraordinary General Meeting of Shareholders on November 07, 2016 and the shareholders voted to split the B2C consumer side of the company from the B2B business side. It is too early to know what this means for consumers.
Here is part of (Google's dodgy translation of) Topfield International's News page. Words in red are very poor 'English' translations.
Ltd. Topfield (the "Company") is at the Extraordinary General Meeting of Shareholders held on November 07, 2016, our digital set-top box business of the B2C division ( "Division Target business part") split by the Corporation Topfield International as a split estate our company is founded and bar hayeotneun determined to survive, this matter is as simple division, spin-off, our capital is not reduced despite the split matter.
