Hi! I have a Pioneer 106burner with latest firmware. Xp with latest Aspi. my problem is that when i write simple datas on any DVD-R (Princo, That's write, Verbatim)(tried UDF, ISO, UDF/ISO - Nero 22.214.171.124, Stomp Recordnow max 4.5)these discs are not readable by other PC DVD drives. i tried : Pioneer Lg Samsung Liteon ...on my PC and on others PCs too. Some of these drives show me the files , but most of these are corrupted and it hangs. The only hardware capable of reading perfectly those discs are my Recorder and the Xbox(Samsung drive inside) The strange thing is that when i burn Video DVDs, containing VIDEO_TS, AUDIO_TS, the Dvd-r (same brand)works perfectly on all readers.... Isn't it UDF/ISO too?We'r talking of files, what is the difference?Why DVD-R with a movie on it works perfectly? Can't understand.. Any advice?
