I don't know why but i get different results with almost the same hardware.I mean i have the BTC DVDRW 1004 FW:0038 and i use as stand alone dvd the same SONY DVP -NS330 and a cheap
BLUESky DV2400 and so far i didn't have big problems.Here are some results i can provide you:
TDK -R 4X ( TYG01 ) playable with no errors at all to both of them
TDK +R 4X(RICOHJPNR01) no errors in SONY, some freeze in BLUESky
SONY NO NAME 4X (SONY04D1)no errors in both of them
MMORE -R 4X(MBI) no errors in SONY some freeze in BLUESky
NONAME DVD-R 4X (LONGTEN001) no errors in sony quite a lot of freeze in BLUESky
PRIMEDISK -R 4X(RITEKG04) no errors in SONY some freeze(1-2) in BLUESky
SKC -R 4X (SKCCo.,Ltd.) no errors in SONY quite a lot in BLUESky
SENTINEL -R 4X (SKCCo.,Ltd) same as above
SENTINEL +R 4X(RICOHJPNR01) no errors in SONY no more than 2-3 freeze in BLUESky
RIDATA +RW 2,4X ( RICOHJPNW01) no errors in both of them in 6 rewrites so far
PRINCO NO NAME -R 4X ( PRINCO) I used a lot of them in 16 no errors in sony but some freeze in BLUESky and in 4 of them some instant pixelation in sony and some freeze in bluesky.
I am using DVD2ONE 1.30 for recoding and NERO 6.0.0.23 for burning
So my conclusion so far is that SONY DVP NS330 plays back almost everything you put it in and BTC 1004 is quite a decent writer that works good with many media
