Joel,
Thanks for sharing your home network and AV setup. It was enlightening. I just had one question regarding your DirecTV setup.
I see you have the EyeTV Hybrid connected to the DirecTV via the composite cable (to S-video, I presume). What are your main uses for this setup? To use as a DVR? To login (via LAN) in to the Mac Mini from other PCs to view live TV?
Also, how satisfied have you been with the EyeTV video quality? Acceptable or not?
Thanks again and I look forward to your response (as I have a new Mac Mini and am contemplating its setup),
Brandon (phishee) |

Brandon,
Actually, as noted in the initial post above, our EyeTV Hybrid is connected to our satellite receiver via composite (RCA) both video and audio-wise (the receiver only has one S-video out and that goes directly to the TV).
Thus far we've used the EyeTV Hybrid for PiP (picture-in-picture) as well as to record some video (like a DVR). Regarding PiP, we have the Mac mini/OS X displayed on the TV with a small - say, probably 12" TV equivalent - window in a lower corner that shows live TV (that was part of my wants with the setup: be able to watch sports on TV while having stats, etc., online right next to it). That works well.
As far as recording video, the results have been OK quailty-wise. After video was recorded (various TV shows 30 min. to an hour long, as well as a couple 2+ hour-long movies, all without any trouble/pauses/stuttering), I've watched it within EyeTV, as well as exported it to AppleTV/QuickTime format (.M4V) and watched it within QuickTime Player, and the quality, again, is pretty good, though not quite as good as I had hoped (slightly less quality than is normally displayed when watching TV directly from the satellite receiver). I've not yet tried burning the video to DVD (using Toast 9 Basic that comes with the EyeTV Hybrid), but I'm curious as to whether or not that will be any better. There are all kinds of options as far as exporting the video out of EyeTV, but I'm not familiar enough with video codecs, resolutions, frame rates, etc., to be able to figure out what is best to export to.
I really need to spend some more time researching things as far as recording video (including at the Elgato forum), but I simply haven't had the time to do so. I'm hoping that by reading what others have posted regarding EyeTV (at the Elgato site and elsewhere) I can tweak things until everything is setup as ideally as possible. Don't get me wrong: everything is working well, it just might be able to be working even better.
Edit: According to this post, if I'm understanding what is being stated correctly, the quality issue may be because I'm still working with analog video versus digital (HD) content (i.e., if we had an HD DIRECTV receiver the video being recorded would not have to run through the EyeTV Hybrid's digitizer - instead being recorded/copied straight to the Mac mini's hard drive - and as a result would be better quality, not only because it would be HD, but also because it hasn't had to be "processed"). I could be wrong, though, as I thought that, even though it is not HD, our DIRECTV receiver delivers digital video. I obviously need to investigate this further.
Edit #2: Please read the post below this one for verified-to-be-correct information regarding limitations and ideal setups for the EyeTV Hybrid.
Let me know if you need any further clarification on anything. Thank you for taking the time to register and post!
Joel

As now documented in the post linked to above, there is an explanation for the less than ideal video quality I'm recording using the EyeTV Hybrid. Below is a listing of a brief Q&A regarding this topic:

Sorry to restart a bit of an old post (less than a month, though ), but I wanted to clarify/verify what was stated in the last couple posts in relation to my setup.
I have an early 2009 Mac mini hooked up to an EyeTV Hybrid (with the latest version of th EyeTV software) that is connected to my DIRECTV receiver via composite (RCA) cables. (Note that the receiver is not and HD receiver.) The video recorded within EyeTV seems to mirror what was originally noted in the first post: it is "OK", but not as good as can be normally viewed on the TV via its direct connect to the receiver (S-video with composite audio cables).
Is this due to digitizing/conversion going on, assuming it actually is? I thought for sure at this point that all DIRECTV receivers, even non-HD models, are delivering digital video. Is that not so? I thought that's why I didn't have to worry about the whole US switch from analog to digital TV: I was already covered with my DIRECTV receiver.
I would really appreciate someone further clarifying this for me. Thanks a ton!

Your DIRECTV receiver is most likely receiving digital signals , but on the outputs (no matter if RCA or S-Video), the signal is analogue. And for the picture quality: RCA gives you the worst output, next better choice is S-Video, and the best available analogue signal quality is Component (if available). If you swap cables for a test and connect EyeTV Hybrid's inputs to the S-Video out of your receiver, the quality of your recordings will certainly improve quite a bit. |

Thanks for the informative reply, Andy. I understand what you're saying regarding the analog inputs. If you don't mind, let me double-check one more thing:
If you would, please look at this article, specifically the Digital Inputs sections down near the bottom. That seems to mean that, even if I upgraded to an HD receiver from DIRECTV, I still would be limited to analog input into the EyeTV Hybrid, right? The only way to get actual digital (including optionally HD) video would be to change our TV provider, such as to a cable company like Comcast, correct? But only so long as they offer non-encrypted video (Digital cable/Clear QAM), right? That way I could simply connect, via its coaxial connector, the EyeTV Hybrid to the digital cable set-top box, and the video feed would be completely digital.
Please feel free to let me know if I'm finally starting to get a clue.
Thank you again for your help! |

Thank you for all the affirmative answers. Too bad that would mean major switch-up in our TV/Internet/phone setup...and I don't see that happening right now. Still, at least I now know what would work. I guess that helps explain why just about everyone I've run across that is doing an computer+AV setup like I've got has got cable.
Thank you again for your help!!! |
