You’re right - the scan indicates a non-optimized write strategi for the Mitsui medias (Mitsui is known to produce high quality CD-R so their DVD-R should be of equally high quality). Actually I was thinking of buying this media myself (yeah yeah, I know they are not listed on the BTC compatibility list but since this list needs updating …). Anyway If I were you I would definately stop using this media for now and save it until supported in a future firmware update.
Did you do a Nero Scandisc (surface scan)? This will check if the burned media has any defective sectors. Also a transfer rate test will give you an idea of the burnquality. If the transfer rate graph keeps rising/falling it means that the drive is strugling reading the media. Oh, do always check the media in another DVD-ROM drive. This is in my oppinion a much better verification than testing in the burner itself. To sum it all up:
- Burn the media at the certified speed. If you buy a 4X certified media but can only burn it at 2X it usually means the media is not fully supported in firmware. Try another media or accept the risk of producing a coaster.
- Do a C1/C2 error scan in K’s Probe. Avg. PI/C1 count should be below 280 and avg. PO/C2 count should be very low
- Do a surfacescan using Nero Scandisk IN ANOTHER DRIVE.
- Do a transferrate test IN ANOTHER DRIVE. The graph should start low and keep rising to the very end of the media
Now you know if you have found a good/compatible media for your 1004 drive - or whether you should keep looking. A media that works great for me (except with firmware 0045) is Verbatim DataLifePlus 4X DVD-R. The MID code is TYG01.
