At least that was what another owner had posted. Do you have the A-110? Do you use it 480i out?
I have the A-100 and use 1080i out as my Qualia 004 only accepts 1080i.
The A-110 has HDMI 1.3 and adds lossless audio formats, internal SATA HDD and external USB 2.0 features
I have almost zero 480i original sources. Most of the items I am streaming from the PCH are MKV. The PCH manual is on the Wiki page.
I recently found Playon and am downloading Instant Movies from Netflix via the PCH. It is not HD but the D2 makes it as good as an up rezzed SD DVD.
Read this from the PCH Forum.

RE: Pass native resolution of files without scaling
The point I was trying to make is - that it seems as people in this thread really dont understand what they are requesting with "passing native resolution".
The pch is not a dvd-player which only have to output SD 480/576 i/p - its a media player which can play many media types which have been resized and cropped to all kinds of non standard resolutions. Like the many resolutions Heartware mentioned - but not restricted to those, any non standard resolution would also play.
Requesting a "pass through of native resolution" doesnt make sense because
1. you cannot output non standard resolutions, you can only output either standard video resolutions or standard pc resolutions.
2. your scalers would never accept these non standard resolutions if they were indeed outputted, your scalers only support input of standard video resolutions (and possibly some pc resolutions depending on scaler used) like those being outputted today.
3. The NMT/PCH allready output non scaled for all standard resolution files and for all files with standard horisontical resolution.
Pass through of native resolution only makes sense if native resolution are in fact a standard video resolution like 480i/p, 576i/p, 720p, 1080i/p - and in these cases the PCH allready do output non scaled - but many times native file resolution are not standard resolutions in the case of the PCH.
Thus for all the files which have non standard resolution, the pch would allways need to output these files at a standard video resolution. This is normally no problem, as a file with for instance 1280x544 would just get added black borders to fill the resolution to 1280x720 for 720p output. This means no scaling is actually being done in the PCH and you allready have what you ask for. The same for SD if horisontical resolution are kept standard and only vertical resolution are cropped.
The PCH only does any scaling if the resolution are something non standard - like 640x242, then it would need to scale to 720x480 before outputting at 480p. But if it were not scaling as people here suggest, then your scalers would not accept the input anyways making the request for this redundant.
So basically - everytime the PCH need to scale a file before ouput because the file has non standard resolution - then your scalers would not accept the resolution if the PCH did not scale it. And everytime the PCH do not need to scale because the file are allready in a standard resolution, or only needs to add black borders, then your scalers are allready receiving a non scaled output from the PCH. Ergo either way the request for passing "native resolution" doesnt really make sense.
As for deinterlacing in case of SD DVD material - which is different from "passing native resolution" - I understand why you would like to be able to ouput the interlaced signal for deinterlacing in your Reon scaler. And I dont see any major problems in implementing a possibility to do so in the NMT.
As for automatic switching of ouput resolution based on file resolution (which really has nothing todo with the "passing native resolution" request ) - it is not simple to implement because as described the NMT/PCH are not restricted to playback of a few standard resolutions like your common dvd-player, but can play any file of any resolution (more or less), this plus the risk of outputting something not supported by the monitor leading to black screen if it switches automatically and the different possiblities in the connection types, does make this request difficult to implement. But if it is to be implemented (and this is still being investigated by Syabas to be done if possible), I fully agree with Heartware on the method to do so.
As a defense of the NMT/PCH I would also like to point out that the way this works with fixed output are the same as any other player works - other players also do not autoswitch between several resolutions (except for the minimal switching between PAL and NTSC SD possible in some dvd-players). Other players, bluray players, media center PC's, digital tv receivers etc. works the same way by outputting a fixed output and connection type of the users choise. Therefore I dont really understand why the scalers should be especially useless with the NMT, you should all have the same issues with all other types of devices attached to your scalers.
My reason for these comments - is to make it more clear what is really being requested in this thread - is the request to "pass through native resolution" (not really possible or usable), or is the request in this thread for "automatic switching of standard outputs based on file", or is this thread about adding a 480i/576i output mode to allow for external deinterlacing of these specific resolutions ?
