Very well I will allow you to review one home video out of the five, but you must tell us upfront which one that you will be reviewing. We might need more time then due to the process especially if we want to keep producing at the same quality that we have been so far.
have been与表示职业的名词连用，用来询问或说明某人所从事的职业，但这里的the same quality作havebeen的宾语并非表示职业的名词，那样怎么样理解havebeen这里的使用方法？
the same +抽象名词+as/that 从句时，same的“同一个”和“同样的”的意义重合，不再有不同。此时从句用as引导还是that引导，取决于从句的结构，即从句用比较分句结构还是关系分句结构。比如：
Tom has the same problem that I have. 关系分句需要有完整的主谓宾结构，一般不可以省略成分，也不可以使用动词替代。所以这里不可以用助动词do替代have。
Tom has the same problem as I do/have. 省略和替代是比较分句的常规。
We want to keep producing at the same quality that we have been producing at so far.
that作为关系代词引导关系分句，并在从句中作介词at的宾语。介词不可以省略，谓语的目前完成进行时也不可以缩减为have been.
We want to keep producing at the same qualityas we have been so far.
as引导比较分句，分句中与主句重复的成分均可省略。
非常显然，网友这个句子中the same quality后的分句显然是比较分句结构，作者却错误地用了关系代词引导从句，致使关系分句结构错误。应将that 改为 as。
