As far as I know, the sources that exist for TPM are as follows:
-Japanese Laserdisc
-Official DVD
-schorman’s HDTV preservation
-Official Blu-ray
-Theatrical DTS CD-ROM
Is there anything else that could be used to create a BD ISO for the theatrical cut of The Phantom Menace?
There is also:
- Z bootleg
- theatrical VHS
- theatrical VCD
- Adywan’s reconstruction
- theatrical ORF Ein PAL broadcast
- theatrical ORF Ein HDTV broadcast (was recorded by at least 2 people but not shared nor uploaded)
- lot of HDTV captures in several languages (Spanish, German, French, Russian, Polish, …)
- some HD bonuses featuring theatrical scenes not available elsewhere (palpatine’s office, full theatrical podrace)
I’m currently working on a HD theatrical reconstruction, since it seems that previous projects were abandoned. The entire process takes time but is already well advanced and I’ll post news here as soon as possible.
