    Shadowlayer: I don't know about your people in 'the scene', but a CFW based on 3.52 has been around for weeks.

    So if I get this right, you can't use this on a regular SDTV?
    That sucks so much...

    The lastest exploitable FW is 3.5. Eventually someone will figure out how to hack the new model, they just remind you it could be awhile.

    For games TV out you must have a EDTV or HDTV as it requires Component Video 480P.

    Does anyone know if the TV out cable is going to be released for the original model? I've heard rumours that it's not a new capability just that sony are using the release to push the new TV out cable.

    As far as I'm aware there is no place the required video signals come out of the unit. Custom hack kits can tap the required signals and add an output port which connects to another device for TV out but they suck as they seem to drop lines. So TV out really is a new feature, and a nice one even though I heard it letterboxes rather insanely. I'm guessing they centered it, so you have your 480P picture frame with a 272 lines tall picture in the middle.

    The new PSP has modifications to allow it to output to a TV. The old model does not have the functionality unfortunately.

    Can anyone say if the screen is faster or not? That's all I care about.

    It's apparently better, but I have not heard any definite confirmation that it's less blury. If it is, then consider it bought, Tokobot for example is painful to play because of it.

    It sure is a lot slimmer, and the TV out capability is cool. Possibly you could watch PSP movies on TV? Like downloaded anime? :p

    I still don't know though. I just got my PSP in April. I probably won't get this one.

    The TV out is intended for watching/listening to stuff on your Memory Sticks or UMD music/movie discs. You can do that with any of the video cables. For PSP games though, you must use Component 480P.

    So you could use it as a small media player. Also when the system is eventually hacked, I wouldn't be surprised if someone figures out how to get TV out from games to not be letterboxed or enable it to run without 480P.

    PSP games are developed for the screen on the PSP, which is progressive. I don't think there is an easy way to turn that into interlaced output, otherwise Sony woukd allow it in the firmware themselves.

    Well I'm not familar with any technical reason as to why you can't. As far as I'm aware, a system like the PS2 has games that can either be run in 480i or 480p if they program in the option. And as far as I know that's all there is to it, and there is that boot disc out there designed to help you force games into those modes.

    So I don't see why you couldn't just interlace for games. Afterall you CAN interlace for everything besides games! Seems awfully silly to me that game programs are somehow different than the XMB program. If the XMB can be output interlaced (which since they have RCA cables we know it can) then why couldn't a game?

    I have to fully check into this but actualy the PSP LCD is Interlace, not progressive.

    I think Video Game out was a quick feature they put in but not the primary cause for the video out development (i say more so to boost the failing sales of UMD Movies). I think in a few firmware updates they will get it all sorted out.

    Why would the PSP output a progressive signal in games then? It makes no sense.

    I've never heard of an LCD being "interlaced". I'm pretty sure PSP is a regular LCD which is 480x272. If it were interlaced it would look like ASS. If it were something x480 then maybe I could see interlaced. Anyway, there is no reason games shouldn't be able to run interlaced. The game code isn't impacted by how the system outputs video frames. It's not like you're choosing between resolutions to run the game in. The game runs at 480x272 reguardless of what you would be outputing the video signal as.

    I think Sony just doesn't want you gaming without 480P, perhaps because it would look really shitty interlaced? Since they are using 272 and your TV is 480, you can't double that up nicely, and you can't use non-interlaced 240p type display. So they are going to have 480i or 480p, and in games they say it has black bands like letterboxing. So they probably center the 272 picture in a 480p frame. Maybe in the XMB they stretch to fit?

    Either way TV-out got less appealing as it became a reality. Now that I think about it I understand why those 3rd party devices dropped scanlines, because the line count doesn't really fit.

    What on Earth are you talking about?

    A link for you http://en.wikipedia.org/wiki/Interlace

    Progressive signal pictures are not easy to interlace for non-progressive displays. It would cause all kinds of problems.

    I don't understand your point. The PSP has a framebuffer. This frame can be output however the hardware they put in it desires. Why couldn't they output interlaced video? Clearly, they CAN. Otherwise how would they be offering regular Composite Video cables for TV out? You can't do 480p progressive scan with Composite video.

    The whole thing is how stupid it is that they allow you to use the Composite Video/interlaced video out for your Media, but force you to use 480p component for games. I'm just guessing it has to do with the odd resolution. Again I just find it silly that you cannot output 480i with psp games and I don't see any technical reason why it couldn't.

    Isn't UMD video natively 720x480 and downscaled by the PSP to 480x272? maybe because the video is being pumped out by the PSP at it's native resolution rather than resized so it has to be interlaced.

    so the UMD has untapped resolution potential? what a waste of storage space that would be.

    UMD Video is encoded in 720x480 pixels resolution, which is then scaled to the 480x272 pixels PSP screen resolution. This way it will be possible for further products in the future to display UMD Video on larger screens and/or TV's at full DVD resolution.
    Used Codec: H.264/MPEG-4 AVC Main Profile Level3 (Memorystick-Video uses: MPEG-4 SP,AAC)


    That's what I saw when I did a bit of googling.


    I didn't hear anything about restrictions when using 480P. As far as I've heard 480P can be used with UMD Videos, Games, Media, etc.
