Can you guys tell me one thing ? If I encode a video of resolution 320*240 then will the dell x51v stretch it to full screen in WMP ?
Is it applicable with TCPMP too ?

TCPMP is able to strech to full screen.

WMP most certainly does not...TCPMP is the way to go.

Yes dell axim x51v supports full screen under the resolution u mentioned. Video is smooth too(just like X50v)

**I guess hx4700 is the remaining culprit

According to Microsoft on WMP10, it depends on the "device and the codec that was used to encode the content".

Meh. I have yet to see an actual WMV file that WMP will stretch. TCPMP is far superior.

What's Better encoding to 320x240 or using the screen native res of 640x480? You'd save a bit of size on the file but would you be sacrificing Detail?

An easy test? A google for a write up on pictures of the same thing taken using different resolutions. Best viewed on a desktop for the full effect.

TCPMP also support the graphic chip on x51v, which makes the video playing smoother.

Not just that. It's more battery efficient too. :)

I'd like to add that a stretching a QVGA video on a VGA device will take up a few more CPU cycles - i.e. battery consumption will be higher, though the difference is minor. The difference is apparently more obvious when the video in question does not fit the screen multiple e.g. 572x384.

> WMP most certainly does not...

I think you are mostly wrong. WMP scaled to fullscreen, so does PocketTV Classic (freeware MPEG player) by the way, too. and of course TCPMP too.

And they all use hardware accelerated scaling, so the image quality will be gorgeous with all those players.

not if it is done by a video accelerator, which is the case of most VGA devices, including the x51v.

That's odd because I've never managed it.

The x50v/x51v are the only PDAs with a video accelerator worth mentioning, so to say most VGA devices is a little bit misleading - I wouldn't count the ones on either the Toshiba e830 or the hx4705 as really worthwhile, and none of the rest of the VGA devices have one at all.

Can anyone post a link to a video that is 320x240 and scales using any version of WMP? Then mention what device/os/wmp version that successfully scales the video?

No WMP does not scale a 320*240 video in PDAs like hx4700. However as users pointed out that Axim X51v/X50V uses pixel doubling techinique to make the video fullscreen

**TCPMP as-well-as PocketTV,both, make the video of 320*240 full-screen even in VGA devices

I think this is a bit misleading - the ATI graphics chip is supported by, for example, TCMP and its video playback is on par with the x50v (plus better screen and battery (sorry..!)).

Not knocking the x50v though - just thought people interested in video playback might be a bit misled.

Thanks for the correction regarding WMP (which cannot scale up to fullscreen, apparently).

Yes, The ATI graphic chip is present in several devices (VGA and QVGA), and it is also supported by PocketTV.

Some of the new VGA devices have a video chip from nVidia, and applications can use of DirectDraw to get accelerated scaling. At this time I think only TCPMP support this, but we plan to support it in PocketTV.
