I didn't try ultima, but on PVR9090x you can check this firmware: s9f2a126-11091F.sgn It can record as MPG format, and you can play it on PC, and vice versa. Find it here: _http://hv-softwares.ifrance.com/sw/29E3USB_CAS.zip Enjoy.
I have a Hivion 9090x Ultima. this file is much smaller than the usual firmware files for it and I can't get it to load.
I'm having a lot of trouble trying to use the PVR options on the receiver with a new Samsung Story Station attached to the rear USB socket. The picture picture jumps and the unit stops responding to the remote.
