The Revo doesn't have a serial port, so my IR sensor will no longer be usable. However, the HD-PVR has an IR sensor built-in, and from what I can gather, there is support for it in lirc, but this support is kind of an in-progress thing. I want to use Mythbuntu for my myth system, and upgrade the lirc drivers to handle the HD-PVR sensor.<br>

If this is not an issue, that means I can go ahead and order the Revo with the knowledge that I'll be able to get it working with not too much pain and suffering on my part.<br>

Not sure if that's an issue with the hdpvr driver or the lirc_zilog driver at this point. I don't actually use my hdpvr for much of anything at the moment, and haven't had time to dig into it.<br>

</div></div>Yes.<br>

</div>Don't load lirc_zilog, or rewrite lirc_zilog to be interrupt-driven. (Not even sure if that's possible... It'd definitely be preferred if it was though).<br>

</div>Non-functional IR receiver. If you're not polling it, you're not going to see any incoming IR signals.</blockquote><div><br></div><div>Sounds like it's unknown whether this lockup affects all HD-PVR+lirc users or what the frequency is, or when you'll have time to look into it. Fair enough. It's not the answer I was hoping for, but better than no answer. I still think I'll go ahead and get the Revo, and if I experience the same thing and it isn't too hard, I'll try to help debug it.</div>
