The Firmware Page

Well i bought this burner today but when i went to search for a firmware, i saw there was no model with this name in Liteon's website.
its shows as "ATAPI DVD A DH20A1P ATA DEVICE" on windows.
Is this the same drive as other but with a diferent name?

these are the new Philips LiteOn drives, there is no new firmware, way to early

still is it normal i dont find any info about it on liteon site, although i find other new models in their database?
think its kinda weird, thx for all ur help so far.

@ pixa,

It appears that you have failed to look in the correct place on the LiteOn Web Site for information concerning the LH-20A1P DVD Burner. The below LiteOn Web Site Link provides a download link to Firmware and User Manual for the LH-20A1P DVD Burner ->

Dont think DH-20A1P is the same as LH-20A1P, unless they r the same model with diferent names.
Already tried LH-20A1P firmware and it doesnt detect the drive, but thx for ur help =)

Surely that is the same hardware, but OEM!
And you cannot crossflash using official flashers.

Try LtnRPC to make it RPC1.

Its the new collabration between liteon/philips, there a few drives out now from them

Hey All

You can Cross Flash The DH-20A1P to the retail version of this drive which is the LH-20A1P.

1. Download http://www.liteonit.com/DOWNLOADS/ODD/LH-20A1P/firmware/DR20KL0N.zip

2. Dowload http://codeguys.rpc1.org/utilities/Flash_Utility-2.0.1.rar

3. Follow these instructions http://club.cdfreaks.com/showthread.php?t=190420

This is what i did and works PERFECT!!

KubantuWHacked

correct, there the same drive, just the DH-20A1P is an oem

This is much to complicated, follow my link below & download the Zip file.

When you launch the firmware don't forget to TICK the UPDATE BOOT CODE box.

Follow the prompts. You will get a few warnings but carry on.

Job Done

Halow all.

Here's the thing, I'm gonna try and keep it short. I've been trying to burn video files to DVD for over 2 years now with no succes whatsoever. It's been frustrating to say the least but I finally came across a program (avi2dvd) which has gone some way to the burning actually getting somewhere. Once I converted the avi to dvd I tried to burn the image to disk using Nero and imgburn but both programs failed displaying a 'power calibration error' message. So I took this previously posted advice shown here...



Am I right in diagnosing the problem correctly in that it's a firmware problem with my dvd (dh-20ap1) writer? I'm using dshirt dvd-r. I've tried diasbling inapi and blowing on the lens. I'm obviously sceptical about using the flash utility as it's an experimental procedure and I don't want to break my dvdwriter but it's the last thing to try. I will try it if this is indeed what is stopping my burns. So do i need to tick the update code box with the flash utility? Any help much appreciated.

Westons (pint) mmm

more likely this is your problem, buy better media

Bit embarassing really, don't think i'm very good at this malarky

Are you saying this dvd writer is a bit snobbish: it wants nothing but the best/most expensive disks? If so, what brands of media would you recommend for it matey?

verbatim are the best really, on a personnal note, i used alot of CMC Mag media id on that liteon model, without issue, that 20A1X and 20A3X series is one of the best liteon done, and also for quality.

Also make sure your drive is in UDMA for the drive, check device manager, under ata/atapi controllers

Ah, I own some Verbatim CD-RW's, I'll check out the DVD-R's thanks.

Not sure I understand the last part about the drive. I went into the channel properties under ata/atapi controllers and saw that the transfer mode for each is set to 'DMA if available'. Is this what you mean?

yes, is it actually using DMA?, and not PIO

Can't see PIO mentioned anywhere. The primary IDE channels state -

'Device type = Auto detection'
'Transfer mode = DMA if available'
'Current transfer mode = 'Ultra DMA mode 5'

Secondary channels are the same apart from the Current trasfer mode which states 'not applicable'.

thats fine, try with better media

Thanks for the help mara, I'll let you know how I get on. Hopefully the 2 year wait will be well and truly over.

Verbatim disks worked a treat, though there is skipping on my Tevion DVD player, however the disks playback fine on a playstation 2. Next step is to invest in a decent DVD player.

Thanks again

Very happy chappy
