(atidtuxx.sys) I have a copy set up on my system and appears to be working properly.. If anybody would like to test, I can send them the file off-list. Again, this is for the ATI HDTV Wonder card, not the AVerMedia A180 card. Thanks for you help Jon :) I'll be doing more testing later tonight, and report any results/errors. It would certainly be cool to get some feedback on my findings, and get the firmware script updated for others. -------- Original Message -------- Subject: Re: Nextwave NXT2004 Firmware (found) Date: Tue, 26 May 2009 18:13:59 -0500 From: Jonathan Isom To: Michael Akey References: <4A1C711E.3070408@onid.orst.edu> On Tue, May 26, 2009 at 5:45 PM, Michael Akey wrote: > (posting to proper mailing list as per linux-dvb@linuxtv.org's > auto-response) > > I recently acquired an ATI HDTV Wonder PCI card from a friend of mine > and decided to test it out on my satellite TV transcoding server to also > get OTA channels.
