Hi all, I have browsed the forums and searched, haven't come across quite the same problem I am having though, so I am hoping someone can shed some light on it for me. I have a Pioneer A05, had it for about 3 weeks. I burned the 4x DVD-R that came with the unit (a Maxell piece) without a problem, so I ordered some Memorex blanks after enjoying success with them on the CD-R format. I have burned one movie which seems to play fine until about 10-12mins from the end where there is some visual distortion (pixellation, jerking etc) which does not impair viewing a great deal, although there is obviously a problem. I also burn backup discs, and I made myself a 4.4gb collection of mp3 data, and burned away at 4x. The burn process seemed more akin to 2x (it took 30mins...) and upon completion I tried to acrhive the disc in my WhereIsIt catalog - only to discover the files toward the end of the data set (approx 3.9gb - to the end) did not read, and could not be accessed in any drive I have tried. I have ordered the sample DVD-R pack from blankdiscshop to see if I get better results from any of those 7 supplied, and I am currently using firmware revision 1.33B ('hacked' to allow 2x burning on some 1x media) - although I have only just started with this particular one in an attempt to get better results from my Memorex's. I haven't burned ONE successfully yet, in about 8 attempts. The only one that works ok is one I tested with approx. 3.7gb of data and burned at 2x in Nero. The supplied Maxell DVD-RW I had is also fine, and i have re-written this a few times now, so I am pretty confident there isn't a problem with my A05 unit - it's just the Memorex media (supposedly good with A05 reading most sites such as blankdiscshop), perhaps I have a bad batch of them (25 spindle, says 4.7gb 1x-4x on the packaging). Any thoughts/advice appreciated!
