The laser in my V7 finally took a dump so I got a replacement. Popped it in last night and it won't boot DVD-RW (Memorex) or CD-R (Sony and Verbatim). All originals boot fine so I thought maybe something on the install came loose. Strangely DVD-R backups work fine... Can anyone give me some things to try here? Keep in mind, before the original laser crapped EVERYTHING booted perfectly.
